If you have a huge difference in gravel build-up between the first and
second run groups, no amount of sweeping is going to fix that problem. It's
the surface that is falling apart and you get more loose gravel with each
run group. I'm not saying sweeping in the morning is not good, but the only
people who benefit from that run in the first run group. There is no way
you can milk that for several events.
