How much running do the CCs do during beast? Do they run every day? If so, how many miles usually? Do they normally run in running shoes or do they run in their boots? How often do they run in their boots? Which do they do more of during beast - ruck or run? Do they also work up to rucking with a 40 lb pack? DD has been working mostly with a 20-25 lb pack and is doing well. I picked it up the other day and, frankly, my old body could not imagine carrying around a 40 lb pack for more than a mile or two.
