We’ve not done anything that physically demanding, but we’ve definitely had events with short hikes, a chair lift ride up the (summertime) mountain to the lunch spot, or other short diversions from large group discussions. I’ve never gotten any sense that if someone were either physically unable to perform it or just not interested that it would be held against them and in any group of 30+ people you’re likely to have someone who doesn’t want to/can’t do exactly the activity and so you make accommodations.

It’s not like you’re going to be coding while waiting for the next set.
