Our little group has an "A" ride and a "B" ride, and it is set up so the B's leave with a 10 minute head start and the A's chase. We get to our half way point together, and all start back together as a pack, so people can hang as long as they can with the A's, and drop off and reform a B group as we return home.

Even with these two choices, no one wants to admit that they are a B. We have A guys join the B group going out, so they are fresh to hammer the way back, but exhaust the B's who try to keep up. We have B guys that join the A group, and get shucked on the first hill. So even with just two choices and a plan, people refuse to plan for harmonious function.
