Loading the device, PBUS, and never letting go of the brake hand
Equipment: Belay device and locking carabiner per pair
Demonstration:
How the device works, how it is loaded, and then the COMPLETE buddy check in order: climber, harness, knot, follow the rope and confirm it is the same rope, belay device, carabiner, harness, belayer.
The commands, because a belay without them is half a system. Insist on names with every one.
Practice:
Give all the participants one side of a rope, and have them practice loading the device. Once they have loaded the device, once coach should walk through the buddy checks with them. Then have them take the rope out of the ATC and carabiner out of the rope, then do it again. Have them continue to practice until they get it right 3 times - talking a coach through the buddy checks each time they complete the setup. Coaches should walk through the line of participants, giving 1:1 attention where needed, but making sure 1 coach is always free to help with buddy checks and resetting.
The ground round, everybody at once. One device and carabiner per pair, and two ropes tied together so the pair has a long enough line to work with. PBUS on the ground with no climber until the hand sequence stops needing thought, the partner on the far end taking the load and calling each step out loud while they watch the brake hand, then swap. Both coaches walk the pairs. Nothing in this half queues, so run it with the whole group.
Then the wall, and this is the part that strands a class. A coach backs up exactly one belay at a time, so two coaches means four athletes on the ropes and six with nothing to do unless you have already given them something.
Set the ropes up side by side, the two carrying climbers beside the ones tied into loops, so neither coach has to turn their back on a belay to see the rest. Then run three stations and rotate every eight minutes:
Ten athletes is five pairs through two rope slots, so three rotations gives every pair a turn and takes twenty-four minutes. Whatever is left in the block is a second turn for whoever needed one.
Tell the climbers on the rope to move slowly and to stop if the belay falls behind. A fast climber on a slow belay teaches the belayer nothing except panic.
The brake hand comes off during the slide. Back to the ground, no climber. This is the one thing that cannot be half-learned.
PBUS will not come together. Switch to the rowing technique and let the sequence arrive later.
The rotation collapses and everybody crowds the ropes. Give stations two and three a finish line rather than an activity: ten clean cycles, or a traverse there and back.
Both coaches are tied to a climber and the other stations drift. Drop to one rope and put the free coach on the floor. Eight athletes moving through a station somebody is watching beats six who have stopped.
