I've always thought that on steeper courses weight was less of an issue. On your typical NASTAR course, set on a blue with basically no technically difficult turns, doesn't weight equate to more speed? Also, what about the hills we have in the midwest where we try to make them longer by lengthening them into the flats at the bottom. My beer league hill is steep at the top, first five or six gates, and flat on the bottom, five or six gates. The key, obviously, is not to get late on the top so as to not lose any speed. Also you need to carry that speed at the bottom.
I've seen some of our better women racers use diving belts.
Should I eat more cheese burgers and wash them down with pale ales?
