The 100 miler is a 10-times out-and-back on a flat, fast river trail with about 75% shade. The 50 mile is five out-and-backs. The 50K uses a short out-and-back followed by three longer out-and-backs for a 31 mile total. Manned aid stations are located approximately every 5 miles.

Finisher buckles are awarded for all four events, with the 100 mile buckle the largest. Awards are given to the top female and male finishers in each event. Time cutoffs apply: 36 hours for the 100 mile, and 34 hours for both the 50 mile and the 50K.

Shirt availability is based on registration timing; registration by August 27 guarantees a shirt, though extra shirts may be ordered with no size guarantee after that date. There are no refunds. Deferrals to the following year are allowed up to 30 days before the event. Event changes or drop downs are not permitted after races have started. The 36 Hour option does not use DNFs and awards correspond to the mileage achieved. Visit the organization's website for the most recent information.
