Is it possible to see what percentages of endurance racers are signing up for sprint races as well? I suspect the popularity of the endurance series is based on the fact that registration is only $60 for 30 minutes of racing versus $150 for a 12 minute sprint. A rider also gets more practice for endurance than any sprint race. This would also explain why the club has seen the average revenue per rider has fall from last season.Originally Posted by oldtimer
