around here the local "tour de doughnuts" is a similar but shorter race. In the doughnut tour though you get 5 minutes off your time for each doughnut you consume. Strangely enough, the ones who did the longer distance and ate the most doughnuts to compensate for the longer distance all looked distinctly green as they crossed the finish line. I fear coffee would do the same for me. But good luck with the race as long as you don't have to drink 6 cups of coffee as well.
