NOTE: This series is about belaying in single pitch sport areas. Technique changes for multipitch and trad scenarios. This ain’t trad school.  Trad is a whole different ball game y’all!

FACT: The failure to catch a climber’s fall and make it SOFT is probably the #1 reason why people don’t like climbing with you.

You can be a kleptomaniacal serial killer and people will still accept belays from you if they can count on your catches to be soft.  Conversely, your climbing buddy may be your condom/dental-dam-free monogamous sex partner of the last ten years, and then when it comes time for a belay, they always seem to be… with someone else.  What makes that person so great?  It’s cause they can give a soft catch and you can’t.

What is a soft catch?

A soft catch occurs when you spread out the area in space and time for the climber to decelerate at the conclusion of their fall.  The main purpose of the soft catch is to keep the climber from rocketing back into the wall.  The phrase connoting it, “soft catch,” makes it seem like the main point of the soft catch is that the catch has the nice, comfortable side effect of making a fall feel more gentle, like coming to a stop on an elevator.  But that’s actually not the main reason sport climbers do it.

Part of the softness of the catch comes from that specially designed rope you bought.  The other part comes from you.

The rope is not stretchy enough to avoid all serious climbing injuries.  Just relying on the rope, and not making the catch more dynamic with your own action, introduces some serious problems. (They’re more serious in trad, but this is not an article about trad.)

Why is a hard catch dangerous?

The reason a hard catch is dangerous is because it swings the climber toward the wall, not because it’s an uncomfortable jolt (you’re climbing on bolts, so the threat of ripping out trad gear isn’t the issue here).  This swing into the wall introduces TWO independent dangers.

First, the velocity of hitting the wall can be enough to break whatever part of your body runs into it.  Climbers may hit the wall with their ankles, hands, hips, or in the case of an inversion, the backs of their heads.  The most common injuries are those to the ankles.  The more tragic cases involve climbers who invert while falling and hit the back of their head on the face with enough force to kill them.  Sport climbers often don’t wear helmets, so a soft catch can be enough to save your climber’s life.  Conversely, a hard catch can be enough to kill them.  You probably have a climbing friend of a friend who died or was seriously injured this way.

Second, by swinging into the wall, the climber may hit objects they wouldn’t have hit otherwise.  A soft catch results in a climber drifting down rather than in toward the wall, even on overhanging routes.  Belayers sometimes mistakenly give hard catches because there are ledges–but sometimes, a soft catch will cause the climber to miss the ledge entirely, and a hard catch will guarantee that they will hit it.  It’s counter-intuitive, and thus an easy mistake for new belayers.

So how do I get good at giving a soft catch?

You practice doing it over and over until you get good at it.  Do it in a controlled environment, like a climbing gym, where you can catch one fall after another.  If you do it right, you will end up far into the air (e.g. five or so feet of space between your feet and the ground) and the climber will feel a noticeably comfortable stop.  On a vertical wall, they will not need to use their legs to brace against the collision with the wall.  Keep doing it until you can nail it every single time.

Do it with different climbers as well, so you become accustomed to the feel of the rope and the corresponding timing with different climbers’ weights.  If you’re used to catching a heavier climber, you will probably jump too late for a lighter climber, because you’ll be attuned to jumping at a certain level of pull.

Practicing this with your climbing partners will also make them more likely to trust you, more likely to climb harder, and make climbing more fun.

But how do I actually do it?  Give a soft catch that is?

At the point at which the rope becomes taut during a fall, you jump.  And you jump hard.  Everyone I have encountered who wrote on the subject has described it as a “gentle hop,” but I say “jump hard!”  This may be because I weigh 180 pounds.  In any event, I have NEVER been caught in a fall that seemed too soft.  It would be like a couch that was too comfortable.  Occasionally, other factors will intervene that will cause you to want the catch to be harder (described below), but in general, the softer you can make it, the better.

If you jump too early, then the rope will go taut while you are coming back down, which will moot any effect of your jumping.  Jump too late, and you’ll be pulled up after you’ve arrested their fall.  This means you’ll still fly into the air, giving you only the appearance that you did it right, but the force of your jump will not have actually helped decrease your climber’s rate of deceleration when they needed it.

So timing is everything, as is feedback from the climber about the quality of the catch.

This requires you to:

1. Watch your belayer like a hawk, so that you are in a jumping stance the moment they fall
2. Stand almost immediately beneath the lowest-clipped bolt (or slightly to the side if they are in danger of hitting you or catching your line with their leg)
3. Practice with your climber and get feedback about the quality of your catches

If you are chit chatting away, thirty feet from the wall, then your climber will not make any hard moves and will think you suck and will anxiously await an opportunity to climb with someone who actually takes belaying seriously.

The Exceptions

By default, your catches should be as soft as possible.  There are THREE main exceptions:

1. Your climber is at risk of DECKING.
2. Your climber is on SLAB.
3. Your climber is projecting a route and is working a move over and over and is very close to the bolt on an overhung sport route.
4. (There is no fourth.  There are reasons unique to trad, but I keep telling you this isn’t a trad article, even though you don’t want to believe me.)

A soft catch will extend the distance of the climber’s fall.  If this puts them at risk of hitting the ground, then the danger of a hard catch is outweighed by the danger of decking.  This generally occurs around the second bolt, particularly when clipping.  If the climber is at risk of decking, the belayer will focus their attention on taking up slack while the climber is falling (by taking in rope with the hands and sitting down).

If your climber is on slab, there will be no reason to prevent the pendulum caused by a hard catch.

If your climber is projecting, occasionally the climber will prefer a slightly harder catch so they can work a section without having to jug up.

What about the amount of slack before the fall?

This is a hard point for many to understand, or at least seems so, given how many belay.  But here goes:

DO NOT MAKE THE ROPE TAUT WHEN THE CLIMBER IS ABOUT TO FALL.

Paradoxically…

DO NOT GIVE OUT EXTRA SLACK WHEN YOU REALIZE THE CLIMBER IS ABOUT TO FALL.

Generally, when climbing with strangers, I find that only a third of belayers will handle an expected fall properly, with the other 2/3 divided equally between the two no-no’s listed above.  After shouting, “falling”, you feel the rope go tight, or you see the belayer throw out some extra slack, and you think to yourself, “oh, fuck my life.”

In general, the proper amount of slack to have out, at all times, is the minimum necessary to prevent the rope from going taut.  That’s it.  Burn that sentence into your brain.

As with all things climbing, there are exceptions.  If your climber is in danger of hitting a lip (because they’ve just pulled through an overhang) then it may make sense to pay out extra rope so that they fall into free space–but if you are an attentive belayer, YOU ALREADY DID THIS BEFORE THEY ANNOUNCED THE FALL.  Thus, short of you realizing that you weren’t paying attention, you generally shouldn’t ever have to pay out extra slack when you see that a fall is imminent.

Paying out extra slack before the fall DOES NOT make the catch softer.  In fact, in a single pitch sport situation, it by definition makes the catch harder.

What do you mean by “taut”?

You will generally leave a gentle curve in the rope while the climber is climbing, so that they won’t get short-roped if they make sudden movements.  When you realize they are about to fall, it’s prudent to take in enough rope to eliminate that curve, but don’t take in enough that the rope actually tugs on the climber, or causes the quickdraws to all stick out perpendicular to the wall.  That’s what I mean by “taut”. (Note: when the climber is significantly to the left or right of the bolt, it’s usually better to leave the curve in.  Otherwise, it’s grandfather clock, cheese grater mania.)

In a decking situation, anything goes–the more rope you can pull in, the better.  But it’s an easy beginner mistake to wrongly perceive the fall distance and needlessly drag the climber off the second bolt.  The climber sprains their ankle, and you notice that the climber still had a good ten feet of buffer after the fall is over.

Other notes

Gym climbs frequently have bolts only six or so feet off the ground.  They don’t really serve any purpose besides letting a climber work the first few moves of a route while clipped from above, and for our purposes, they risk the belayer getting sucked into the first bolt at high speed when catching.  If the belayer is at risk of hitting the first bolt, make sure you unclip it after you clip the second bolt, or don’t clip that first bolt at all.  If this introduces any kind of danger in the gym, or on a route bolted like a gym, use a stick clip to clip the second or third bolt (in other words, where the first bolt would be on more conservatively bolted climbs).

What about letting the rope feed through the device to make the catch soft?

Some climbers are capable of making a catch soft by letting rope feed through the device on purpose during the conclusion of the fall.  This is a technique better reserved for multipitch trad climbers, who make up maybe 5% of all climbers, but 50% of internet climbing forum authors.

The technique requires gloves and if you screw it up, the climber will deck.  If you want to learn how to catch falls with this method, you should probably practice in a way that has a fail-safe until you can do it properly.

Because you can’t do this with a GriGri, people sometimes use this as justification for saying that ATCs are categorically safer.  They are wrong.  In a sport climbing environment, giving up the GriGri for this reason would mean that you would be giving up all the safety benefits of an autolocking device in exchange for a catching capability that is both unnecessary and which probably fewer than 2% of belayers know how to do safely.  You may be with a belayer who has gloves and who you trust to pinpoint your fall location and speed with an ATC, but if so, you are probably married to them and (I hope) are not wasting your time on basic belay instruction articles.

The ATC, like the GriGri, and the many other belay machines out there, is a machine among many, geared to some situations and not others.  If you want a cheap tube-style device for sport climbing, get a Jaws.  (There are other tubes with added brake action, the Jaws just happens to be the best I’ve used.)  As with all things in life, people will evangelize certain belay devices because of a lack of familiarity with the others.  The widemouthed ATC in an unfortunate legacy, imported from a world of trad where the ATC’s weight, multi-purpose utility, and ease of braking larger diameter ropes was more useful.  If you’re too cool for the GriGri, learn the munter hitch or the eight, or buy a tube that can catch heavy people on thin sport ropes.  (That rope at the gym, by the way, is fatter and fuzzier, which is why catching people on an ATC may seem heretofore quite easy.)

What about running toward the wall?

Kind of like the opposite of our multipitch trad climbers, there are people who are capable of running toward the wall to control a fall.  This is reserved for a gym environment in a competition setting.  In any other situation, there will be objects in the way (including other people if you’re at a gym outside of a competition), unstable footing, or a high first bolt preventing you from doing this.
