I agree Rick, if the races only last 20 minutes, why not race 5 or 6 times? At least 4 times a day. Sure it is a real test of fitness, but the NFL goes hard for 4, 15 minute periods, Soccer plays for 90 minutes. Either make the race more legs like the LV series had or sail more races in a day. Make it the first to 21 points.
But then again, if it going to be a runaway, then the sooner it is over the better.
