Well remember Doc, a concerted effort like this really needs a leader, someone who makes decisions to make the ride work out best for everyone, at least that's what I have discovered. We have run lines of 50 pairs riding side by side and managed to keep everyone together. The ride captain upfront, another man bringing up the rear with a man or two in the middle all being able to communicate with each other so if someone breaks down, or straggles, if there is a malady along the way, well you get the picture. Sounds like you all are going to be running strong though, more likely knees to the ground, and ours were more relaxed and steady, no hurry, just enjoying the ride and the scenery. Different strokes...
