I often ride in small groups of 2-5 riders. We all are realizing the benefits of drafting but we aren't very organized at it. Stronger riders will often pull ahead of the others and go out on their own. Or instead of dropping back after pulling someone will push out ahead to set the pace. I know how the pace line is "supposed" to work, generally, but I do have a couple of questions. When I come to a hill, even a small one I cannot maintain the same speed as we were doing on the flat. Are you supposed to try to maintain the same speed or just the same intensity? I think it should be intensity but am not certain. Also, if I'm in the lead and my speed drops going uphill , how do I know at what point I should drop back and let someone else take the lead?
