You are allowed to pit at the finish of each lap, when I'm in shape I do not have too. I solo'd 140 miles at one point last year, never stopped, except to switch the fuel valve to reserve.My tank does not hold that much fuel. Oh yea that also goes for my bike.
In races like that are you allowed to refuel and maybe get a spalsh of water?

Its been a long time since I put something to let the guys passing me what my name was, but between getting free jersey prints, and burning up my favorite set of riding gear on my head pipe I went ahead and bought it
