Course and logistics

Runners complete a 10.05 mile loop that includes the Fainforest Creek Connector and the Southside Trail Loop. Each loop features a mix of flat sections, rolling hills, and smooth single-track trail, with about 700 feet of elevation gain per loop. Race distances are completed by repeating the loop: the 50K is three loops, the 50 Mile is five loops, and the 100 Mile is ten loops.

Each loop has a fully stocked aid station at the start/finish area and a water-Gatorade station at mile 4.25 that may be staffed during the event. Time limits for official results are 10 hours for the 50K, 17 hours for the 50 Mile, and 32 hours for the 100 Mile. Finish items are distance-specific: 50K and 50 Mile finishers receive a medal, and 100 Mile finishers receive a custom buckle. Campsites on Friday and Saturday nights are available to runners entered in the 50K, 50 Mile, and 100 Mile events.

Weekend operations include packet pickup and campsite assignments, a brief pre-race meeting, and specified race cut-off points. Visit the organization's website for the most recent information.
