At 8:00am (the top of the hour) everyone starts the 4.25 mile course. Everyone is allotted 1 hour to complete the loop. Thus, for example if you finish in 45 minutes you rest and recover until the the top of the next hour at 9:00 am and you start the 4.25 mile loop again. You must be at the start line at the top of the hour or you are out of the competition. This continues until the Last Man or Woman standing.

Registration is free. We are asking for a voluntary $5 donation to aid in offsetting the cost of using the SIU campus. For the first time this year SIU is charging the club for use of this area, and in addtion the club provides a porta-potty. This race is completely self supported. You must bring your own food, water, and other supplies. There will be nothing provided at the race.
