Technical parts of climbing performance

Foot matching and swapping

You may find yourself in a position where you appear to have your feet in the wrong position for the next move. Rather than making the next move an awkward one it is often possible to shift your feet around in one of three ways, the foot dance, foot match or foot swap – changing the foot that is stood on a crucial hold.

The foot dance requires three footholds to choose from and making a series of moves until you manage to get the other foot on the foothold you want.

There may not be enough holds to simply move you feet around and a more tenuous foot match is needed. Think ahead to place
your foot to allow the other room to share the
foothold and you may be able to get both feet onto the single hold.

The foot swap or hop is needed where the foothold is too small to match on, and there are no options for a foot dance. Place your second foot directly above the foot you want to replace, get the big toe right above the other, and hop. During the hope remove the lower foot and the top foot should drop right onto the hold.

Foot swapping exercises

On a traverses and routes when warming up make foot swaps on every move, remember to try the foot dance, foot match and foot swapping.

As you get more confidence start making more and more tenuous foot swaps, eventually you will have an idea of how small a foot hold you can do this on.

Placing Gear Efficiently

Effective placement of gear comes down three things, knowing your racking system, developing a good eye for placements as well as the appropriate size of relative protection, and using rests where possible to place gear whilst in balance.

The first two are down to hands on experience with your rack and gear placements. You might go through you racking system at home, trying to reach straight for the piece of gear you think of and take it off and replace it in the same position in time each time. Getting to know gear placements is down to time spent at the crag.

You can however practice the hands-off rests we cover in hands off rests section. By being in balance you avoid placing gear mid move in a strenuous position. You may often find that the instant you have placed your runner you find a better position to place it from. Try to be relaxed when placing gear and ask yourself whether if you make another half move you will be in a more balanced position?

When at a rest it is sometimes possible to see a gear placement above. You may be able to judge the size from the rest and select the correct wire and clip it to a quickdraw ready to place, saving time and energy. Some people climb up with the gear ready in their mouths. Be aware that it is quite easy to drop the gear, possibly meaning you don’t have anything to place. Besides, metal plays havoc with you tooth enamel!

Placing Gear Efficiently exercise

Rack up ready to climb and walk along the bottom of a cliff playing ‘guess the placement’. Find a crack and guess the best size of gear. Experiment with other sizes to see if you got the best fit. See section on various gear placements.

You may be able to judge the size of a camming device placement in finger widths; one finger = cam 1, two fingers = cam 2 and so on.Try it and see if it works for you.

Placing gear on lead exercise

When you are leading try to place gear only where you can stand in balance or from a hands-off rest. Place the gear from here and before you leave this position take time to look up and spot the next rest and gear placement. Take the time to look at how you might climb the next section.

This can be described as anticipating the next moves and gear. So ask yourself two questions where you can stand next and where you can place the next gear. Until you can answer these two questions don’t move.

WARNING — Lead climbing is dangerous. Before attempting this exercise it is worth practicing placing gear on your route whilst on top rope, trailing a rope to simulate lead climbing. Make sure that your belayer has the neccesary skill to stop you if you fall!

Racking up for Trad Climbing

Using your rack efficiently is down to dexterity, remaining calm and staying organised. Know what you are carrying, where it is and make sure that when you take something from you rack you return it to the same place. The consequence of a messy rack is wasted time and energy spent looking for the small wires or large hex’s. Racking up well for trad climbing will safe you time and heart ache in the long run.

The first decision you have to make is gates in or gates out, either all the gates of the karabin- ers on your gear loops facing in to your body or away. There is no right or wrong way, just one way or the other, not both.

Racking up on a climbing harness is like belly buttons, you are either and innie or and outie. Not like in this photo both.

The next problem is what to rack where and, for that matter, what to take with you? Again there is no right answer, but there are a few wrong ones. Your personal preference will quickly fall into place but experimenting with new ideas is helpful, especially on those rainy days when you’re stuck at home itching to get out.

Racking up top tips

1 - Racking up for an easy route with a basic rack for trad climbing. 2- Racking up for long and more complex routes with gear arrange small on the left and large on the right. 3 - The same rack as 2 but with the gear arrange wires on the left and cams on the right.

Wires (nuts or rocks)

Everybody has a different idea as to how many wires to take on a route. If you are climbing on a gritstone edge then the chances are you will be able to make a reasonable guess as to the sizes you’ll need and which it might be prudent to double up on. On longer and multi-pitch routes it is better to double up on all sizes of wires, and rack them accordingly, as you will not be able to see the whole route and may need a greater selection of gear.

How to rack even ten wires is a problem, as even this is too many for a single karabiner. To rack twenty, break them down into sets of small, medium and large with between 6 and 8 wires on each karabiner. It’s best to have a small overlap in the sets; so if you were going to have a doubled up rack of wires from 1 to 10, one way to break them down would be:

  • Small – size 1 x 2, size 2 x 2, size 3 x 2, size 4 x 1
  • Medium – size 4 x 1, size 5 x 2, size 6 x 2, size 7 x 1
  • Large – size 7 x 1, size 8 x 2, size 9 x 2, size 10 x 2
Too many wires racked onto a single karabiner will make it hard to select the right one and make you more prone to drop wires off the karabiner as well.

You could switch one of the size 10 wires for a size 11, giving you something slightly bigger. Wires now go all the way up to size 14, but you might have those sizes already covered by other large gear like hexes or cams

If you are going to have a double set of wires it is better to have one set of wires from one manufacturer and the other set of wires from another company. The sizes will be slightly different, giving you a wider range of placements.

How you rack these on your harness is up to you, but stay organised. Some people go for all the wires on one side or split small wires on one side, large on the other.

Sometimes the route might require microwires, or RP. These tiny nuts are the extreme end of protection with many only offering marginal protection due to there size. Often these are places in large numbers so that if some break one may well hold your weight!

There is also a more specialist nut, called a slider, these are often good in very small, almost parallel sided cracks. Seldom used, often on routes where it is known to be the only available runner, as such it is mentioned only for completeness.

Hexes

The best way to buy hexes today is on spectra, it means that at a push you can clip the rope straight into the gear without a quickdraw. For this you will need one karabiner for each hex. If you double or triple up hexes on one karabiner, they are guaranteed to get in a tangled mess right when you need them.

An alternative to hexes the DMM torque nuts.
An alternative to hexes the DMM torque nuts.

Choose your smallest hex bigger than your largest wire and choose two more hexes up to around a size 9 (three is a good quantity). Some people will carry more, others may carry none, prefering cams. Some rock types take hexes better than cams (e.g. some cracks on the sea cliffs at Gogarth, Wales are very irregular and take large hexes in natural taperings).

Another type of semi-passive large crack protection is the Tri-cam, they are also one of the only reliable pieces of gear for quarried shot holes. They’re a more specialist type of gear, mentioned for completness as an alternative to hexs. A further alternative is the DMM torque nut.

Cams

The range of active camming devices seems unfathomable, but not as complicated as you might think. There are three different types of camming device; the original single solid stem, the single flexible stem and the double exible stem, all have pro’s and cons but they all do the same job.

DMM Dragon Cams and a few other manufacturers now have two or more axles on their cams, giving them a greater range between being fully open and full closed, one cam will fit a greater range of cracks but will weigh more. If you are only going to have a couple of cams on your rack, multi-axled models are a good idea.

Cams provide protection in places that would otherwise be protectionless and although they need to be placed with care, once mastered they can be placed very quickly. The invention of the ‘cam’ helped to push back the frontiers in traditional rock climbing. On long routes, alpine climbs or big walls you will see climbers carrying a very expensive skirt of such devices from the smallest to the very largest.

Manufacturers like DMM and Wild Country now make their range of cams in quarter sizes, meaning that you have the biggest selection of sizes. On long routes, where you may place a lot of gear, such as on mountain routes, sea cliffs or big walls, this option of hav- ing lots of gear can pay dividends. If you only took a few multi-axled cams because they have a greater size range you might end up with noth- ing left to place, whereas with a large number of quarter sized cams you may still have a reason- able range left to choose from. This and the doubled over extension sling means that at a push you don’t need to extend the cam.

Which sizes should you take with you up a route? Look out for any wide cracks, or a route description or route name which suggests one. If it is all wide cracks do you need to take small cams? Starting out a new rack you should perhaps own sizes 1, 2 and 3 in camming devices if going for the more common single-axled cam. As your climbing develops you will notice what size cams would be most useful for the routes your are climbing.

The most important thing to remember about cams is that they can walk out of the placement you put them in if the rope moves the stem. Modern twin-stemmed cams have a doubled over sling to extend them, but it is often prudent and sometimes essential to use a quickdraw as well to add another point of articulation and prevent this from happening.

Quickdraws and extenders

A deceptively simple piece of equipment, which is key to minimising rope drag. You’ll want to carry enough extenders of the right length up a route. This is often based on the length of route, how much it wanders about, are there any roof, grooves or corners that you pass.

Sports climbing quickdraws generally have very short slings for bolted routes where all the bolts are drilled in a straight line to the top. But when it comes to trad routes, nature has seldom aligned all the gear placements. We need to therefore take a good variety of longer length quickdraw with us.

A selection of different quickdraw

You will need a set of at least eight quickdraws to begin with, for short routes. Of those you want some long (30cm), some medium (20cm) and a couple of short ones (15cm). It is also a good idea to have a 120cm sling and shortened as an extender like this below, often called an ‘alpine draw’.

Carry a variety of slings both 120cm and 240cm, so you can extend gear a very long way if needed or use them on spikes as you pass. Keep your 240cm slings over one shoulder and across your body, held in place with a screwgate (see below and your 120cm slings across the other shoulder to help prevent the slings tangling. Put your rucsack on before you shoulder your slings otherwise they will be stuck under the bag!

When it comes to racking your quickdraws adopt a system that works for you. Some people have gear on one side and quickdraws on the other. Many leading climbers (because of the amount of equipment they carry) spread them out over all the gear loops.

Something to hold the karabiner for clipping the rope in captive will help prevent it turning upside down (making it hard to clip). A bit of finger tape, an elastic band or castration ring can be used to captivate the karabiner. Some manufacturers quickdraws have a stiched through retainer to hold the karabiner at one end.

Warning – If you use a slings as a quickdraw with an elastic band or simliar to captivate one end, beware that if it gets tangled up in you bag and the sling clips itself through the karabiner (A), then there is a danger that when you untangle it the sling will look OK, from one side (B), but is actually only held on by an elastic band. Check each quickdraw as you rack up.

Check all your quickdraw with captivated eyes to ensure this has not happened. This has cause serious injury and death to some experienced climbers.

By having one karabiner clearly defined as for the rope means that if you were to go sports climbing and take a few falls the karabiner that has been attached to bolt may well suffer from dinks leaving potentially sharp edges. If you were to clip this damaged karabiner to the rope and fall you will probably damage your rope.

Red for rope or clip the rope into the captivated eye end. Either way you need to have a way to ensure you clip the rope into the same end of the quickdraw to avoid damage that might be done by a bolt or metal gear.

A tweak you may find useful where to make a move up to reach a bolt is too tenuous is to make a ‘gripper clipper’. With some tape and your hold cleaning toothbrush you can create one mini clip-stick to add to your rack. An improvised mini clip stick – the gripper clipper, if you need to stretch to clip in situ gear, one of these can be a god-send. Some people now carry a longer (up to 6m) clip-stick around with them; for clipping the bolts on a sports route, placing a rst wire or brushing holds which are out of reach.

Clipping Quickdraws

There are several correct ways to clip a karabiner as a running belay and many more incorrect ways. You may be surprised how many people get it wrong or fumble every time they go to clip a rope into what can only be described as the most common piece of climbing equipment. Clipping quickdraws then is a fundamental skill for the lead climber.

Whilst I have describe a few of the more common ways to go about clipping quickdraws but there are other ways that work perfectly well. The trick is to find a method that works for both left and right handed and forehand and backhand.

Some of the more common ways of clipping quickdraws. A - Using the middle finger to stabilise the karabner and the thumb and forefinger to push the rope in. B - Pinching eh carabiner and pushing the rope in with forefingers. C - A slight alternative to the pinch is rather than using the forefinger to push in the rope, is to use you thumb to push the karabiner up ad sideways onto the rope.

WARNING don’t back clip

Back clipping is potentially very dangerous, as the rope can unclip during a fall. Always remem- ber to rst arrange the quickdraw so there are no twists, then have the rope going into the karabiner from behind and out through the front towards you. If the route traverse, consider hav- ing the rope running out across the back bar of the karabiner, so the gate is facing the opposite way to the direction of travel, this helps to en- sure that in the event of a fall the rope won’t potentially unclip as it is pulled across the gate.

Try to avoid backslapping karabiners as the rope can run across the gate in the event of a fall cause it to unclip see below.

The rope can also fall across the gate of the karabiner during a fall on traverses if the karabiner is round the wrong way. The general rule is to have the spine of the karabiner point in the direction you are expecting the route to take to the next runner or spine in line for short. This way the rope will not run across the gate.

Remember SPINE IN LINE. On traverses try to ensure that the rope comes out over the back bar or spine of the karabiner

If it is an essential runner consider having two quickdraws in opposition or using a screwgate on the rope instead. This is only really necessary on very run-out routes so that there is absolutely no doubt in your mind that the runner cannot become unclipped from the rope.

Clipping quickdraws exercise

Whilst stood on the ground and tied into a rope try clipping a quickdraw within easy reach with your left or right hand, with the gate facing left or right. Then try clipping across your body. Be careful not to ‘back clip’.

Turn the karabiner upside down and try again. Which is easier? Hopefully, you will realise that the upside down karabiner is much harder to clip and in future will take the time to ensure the karabiner is the right way up.

Turn your quickdraw the right way up with the gate facing toward the hand you are going to clip with. Use your index nger to hook the bottom of the karabiner and your thumb to push the rope in. Practice with both hands.

Next try clipping the quickdraw with the gate facing away from the hand you are about to clip with. This time place your thumb on the back bar of the karabiner and use your index nger to push the rope into the karabiner. Practice with both hands.

Try the same two methods (index nger or thumb stabilising the karabiner) but this time clip across your body.

Repeat practicing clipping your quickdraws until you are awless, remember to add some random variety to your practice.

Try the same clipping exercises stood just off the ground on a slab from a position of balance. The exercise will feel harder because you are concen- trating on staying in balance.

Try clipping a quickdraw as high above your head as you can reach, by your head, by your shoulders, by your waist, below your waist and by your feet. Which positions feel easier and harder?

Then try you clipping excercises on a vertical wall and then an overhanging wall. How much harder is it? Did you use you teeth to help get enough rope in your hand?

Warning using your mouth to help gather the rope up has lead to some nasty injuries, from losing teeth to breaking the lower and in the worst case breaking the upper jaw. Climbers do this all the time, just be aware of the consequences if you fall at that moment.

Clipping traverse race

With a short section of rope set up a few quickdraws on a low level traverse, and have a race. Is it easier to clip when the runners are in front or behind you on the traverse, and does this change depending on what direction you traverse in? Try this over a number of weeks, does your time improve? This traversing exercise is good practice for belaying a lead climber too.

Gear Placements – General

Placing good runners and anchors is the foundation of the safe ropework. Poor placements will make your other efforts futile if the anchors are all going to fail. A placement will only be as good as the rock it’s in, loose rock and super cial akes will be poor placements. Follow the three S’s when placing gear:

Solid – is the rock integral to the placement solid?
Shape – is the shape of the placement suitable for the gear choice? Size – is the gear the right size for the placement?

As a general rule of thumb as well there is a hierarchy of gear placements. Although this is often over-ruled by what you can place and how good it is, but if there is a choice.

  1. Spikes, Threads and Trees
  2. Nuts and Hexes
  3. Cams

Gear placement exercise

After reading the skills for placing all different types of gear walk round the bottom of a crag, practicing gear placements, and discuss with friends how you rate them using the following system 1 to 6 numerical system.

  1. You would hang your worse enemy’s jacket on it
  2. You would hang your jacket on it
  3. You would hang your enemy on it
  4. You would hang off it
  5. You would hang your enemy’s car off it
  6. You would hang your car off it

Advanced Gear Placement Exercise

To practice gear placements for trad lead climbing, stand back from the cliff and choose three places where you think you can place gear.  Walk to the first and try to anticipate what gear will fit before you get there. You are going to try and make the first placement fit. This first placement fitting will safe you so much energy on lead rather than hanging around attempt to get half you rack to fit before you find the right sized piece. 

Judge yourself on the time and how few goes it took to place each runner. Under three minutes with first time placements is a good point to aim for in the long run.

Gear Placements – Trees

Trees like spikes, are great placements but not many climbers are experienced tree surgeons so it is difficult to be sure of them. First look up, the tree should look alive, with either leaves or in the mist of winter some fresh buds or healthy looking branches. Then look down to see if the roots look healthy and strong. As a rule of thumb the thinnest diameter of trunk that is suitable for using as a anchor is roughly the thickness of you thigh, If it as thick as your waist then it could be used as a single point anchor. Just like metal spikes tying around a tree low down will reduce the leverage on it.

Gear Placements – Metal Spikes, Pegs and Bolts

Back up in situ metal protection like spikes, pegs and bolts where possible with other protection. Metal spikes and pegs will be most corroded below the surface and whilst you can test to see if it’s wobbly there is little more you can do to check how sound it may be. Rust may appear superficial but hidden below it may have taken hold. Tying off the spike or peg as low as possible will minimise the leverage on it.

A metal spike tied off low down to reduce the leverage on the spike. You can either clove hitch the sling to the spike or wrap the sling round the spike so it prevents the sling sliding upwards.

Bolts are a little different as there may be notes on their history in a guidebook. Knowing when the bolt was placed and what type it is will help your judgement. Stainless Steel is less likely to corrode than plain steel. Resin bolts have a longer lifespan than simple expansion bolts. Some of the bolts on crags are little more than 8mm thick and 30mm long and may have been in place for over thirty years. If the bolts are subject to the salty conditions of a maritime environment, treat them with further caution.

Using different metals for the bolt, nut and hanger can cause an electrolytic reaction which will rapidly corrode one part or other. If the bolt has signs of rust and the hanger doesn’t its an indication of mixed metals reacting with each other. Some aluminium hangers react with the bolt, resulting in oxidisation.

Top: A modern long 10mm bolts versus the old 30mm long 8mm wide bolt. What would you prefer to fall on? Bottom Left: A aluminium hanger that has corroded probably due to mixed metal issues. Bottom Right: A stainless ring and rusty steel hanger, this was only paced for a few month before the corrosion was spotted, such is the effect of mixed metals.

Abandoned Equipment

One way to lookout all fixed metal equipment in a cliff is that is is essentially abandon equipment with a dubious history of use and abuse. Whilst in many sports climbing areas there are voluntary groups that check the bolts and re-equip the routes from time to time. This is not always the case.

Even if some bolts are not that old, there are other issues, some bolts have failed as they have been overused and in soft rock. This has lead to bolts pulling out almost by hand after only 5 years of heavy use.

So look at bolts carefully, do they look OK? Do they feel OK? Do they move?

Gear Placements – Rock Spikes and Threads

When using rock spikes and threads as forms of protection you need to consider the 3 S’s.

  • Solid – is the rock solid? If it is a thread are both parts solid?
  • Shape – is the shape of the rock suitable for the direction of pull?
  • Size – If it is a stand alone block is it big enough to not move?

As a general rule of thumb a free standing boulder needs to be at least twice the size of an adult curled up in a ball, as well as in a position where it can’t be pulled over the edge. For the scientist 1 metre cubed of rock is about 2 tonnes.

The good and not so good shapes that you can get with spike belays.
The good and not so good shapes that you can get with spike belays.

The shape of the spike needs to be angled back away from the direction of force so that the sling or rope that is a round the spike doesn’t ride up over the top and off the spike. To check this make a sawing motion with sling or rope in the direction of the likely load. If it rides up the placement will be comprimised.

 

Checking a spike by sawing lightly with the sling or rope to check if it rides up and off the spike.
Checking a spike by sawing lightly with the sling or rope to check if it rides up and off the spike.

Like any placement, a spike will only be any good if it is solid. To check for this at rst try rocking the boulder, but be aware that if it on the edge of a cliff, it might topple off onto people! If it doesn’t move, try giving it a kick with your foot and feel for vibrations in your hand.

In the case of spikes that are part of the mountain, the size of the ake is often unimportant. It will just be the shape and solidity that are vital.

Gear Placements – Hexes and Tri Cams

The judgement we need to select a placements for Hexes and Tri cams is very similar to selecting a nut placement. First off is the rock secure than then you need to look at how well the device sits in the shape of crack.

How they are placed is slightly different, as both Hexes and Tri-cams can be placed as passive nuts, however they are designed to cam into placement and become more secure the greater the load placed on them. It is also important to seat them in the placement by applying a shock load by jerking down on the tape.

Gear Placements – Nuts, Rocks and Wires

Nuts, Rocks and Wires stem from the original running belay placement for cracks were simply small pebbles, rocks or stones placed by climber as chockstones and threaded with a sling; over time climbers started to drill out machine nuts and use them instead. In modern days various companies make a variety of different shaped and sized wedges. They work by being placed in natural constrictions in cracks, wedging themselves in. The constriction stops the nut from being pulled through. When placing a nut you need to consider several things:

Quality of the rock

Avoid using loose or hollow sounding rock, along with superficial flakes. Check the rock by tapping it with a karabiner, a hollow sound will indicate poorer quality. If it is a flake try moving it by giving it a good shake, or hitting the flake with the palm of one hand whilst feeling for vibrations with the other. However you check the rock remember that you are at the top of a cliff and possible unroped, there is the possibility of people being below, so take care not to send anything over the edge of the cliff, especially yourself.

Checking the quality of rock for a gear placement. Left: Hitting it with the palm of the hand and feeling for vibrations. Middle: Trying to move the flake in different directions. Right: Tapping the flake with a karabiner and listening to see if it sounds hollow.

Natural constriction

To select a good nut placement, you rst need to identify cracks in line with the route you are climbing. You then need to nd a natural constriction in that crack where a nut can be wedged in, and won’t pull through. There may be signs of smoothing/wear and tear on popular climbs, often but not always an indication of a good placement.

Contact area

When the nut is securely wedged in the crack the greater the surface area of the nut in contact with the rock the better the placement.Try or simple turning the wire round or a different sized wire.

When placing Nuts, Wires and rock in a tapering wedge. You also need to look to check there there is a large surface area of metal against each side. Left: Is good with lots of surface area whilst on the right the contact area is less so it may work itself loose easier.

Overlap

When the nut is securely in place there need to be a reasonable overlap between the width of the crack and the width of the nut. The reason for this is that if there is an extreme load on the placement it may simply pull the nut through the placement.

When place a wire look for good overlap, so that the widest part of the wire is bigger than the thinnest part of the crack. The left golden wire has better overlap than the green one on the right.

Seating

Does the gear stay put when left alone? First you must seat the nut securely. Use the other wires on you rack of wires as a grip and creating a shock load by jerking in the direction of pull on the wire. The nut will probably move slightly in the placement and hopefully drop into a snug fit. Then, if you lightly wiggle the wire you will see if it unseats itself from the placement, a well-seated nut will stay secure. Try not to over-do this, as you may end up with yout gear stuck in the crack, impossible to remove.

Get into the habit of jerking the wires into place to seat your wires as if the wire pulls through when you jerk it, only your arm moves. If you pull with your bodyweight to seat a wire and the placement fails, you will fall away from the rock with it!

Seating a nut by jerking the rack of wires down. Do this as many times as it take to get the wire to stop moving in the placement. Test this seating by wiggling lightly on the wires once it seems placed.
