Here's an exciting belayed "high course" climbing activity done by my friends at Group Dynamix (www.GroupDynamix.com). Check out the video below for the action.
I've done something like this in the past, but what I really like about this version is the "Manhole Ladder" (sorry, it's not quite PC, but it's what they're called. (You can find yours at Granger.) The ladder we use at GDX is 14 feet high and about 12 inches wide. It's a super solid one-piece design with sturdy rounded feet and nice smooth rounded "hand holds" at the top (see pictures below).
The ladder is geared up with four (white) multiline ropes safely attached to some webbing around the side of the ladder and top step. Above the climb is a belay-rated anchor with a static belay rope.
FEET TOP for HANDS
In the video the climber was challenged to walk up the slanted ladder - no hands. She then climbed (was lowered) down with the ladder straight up (her choice). I've seen the ladder held straight up the entire time, and with the ladder leaning towards the climber to start. He did hand-over-hand pull ups and then climbed his way over the top of the "overhang" (the support ropes were a bit tricky to get around). With this overhang method we had three support participants on each of the two ropes on the back side (away from the climber) and two on the front side ropes. He then walked down the ladder, still slanted, with no hands.
Overall, I really like the amount of participation you can get from the team. Eight to 12 (or more) people can be in support roles while one person climbs. Pretty cool.
(I know you will also follow all of your protocols (LOPs) when it comes to facilitating a high course element!)
All the best,
