Bike sections are mountain bike only and trails used are generally rated green to blue. There are two transition areas: T1 at Boulevard Lake and T2 at Kinsmen Park. The organizing body operates as a volunteer not-for-profit and typically requires 50 to 75 volunteers. The event policy states all purchases are final with no refunds, transfers or rollovers. Water quality and weather are monitored; the swim may be shortened or canceled, in which case a duathlon format would be used. Visit the organization's website for the most recent information.
