The 50M/50K/20M use a 10-mile loop with aid stations about every 3 to 4 miles; 20M runners do two loops. 50K entrants run an extra pair of loops in the open field at the start to add distance before joining the 10-mile loop.

The youth course is marked with flags around the corn field and will have volunteer guidance.

This is a cupless race; participants must bring their own hydration system. Trail briefings are mandatory. Pacers are not allowed; crew access is limited to the start/finish area. Parking is limited (about 500 spots for 600+ participants) and a park parking fee applies. The event follows Leave No Trace principles and collects food donations for a local pantry.
