Both races are held on the Harrison Campus trail system. Each race features divisions for every ability level, and the courses are designed to include wooded and hilly sections, long and gentle climbs, several areas wide enough for passing, and areas of steep, rough terrain.

Race day schedules are similar with registration open 8am-10am followed by a racers meeting at the start line with wave starts for all divisions kicking off at 10:30am. Lunch, giveaways, and awards follow at 12:30pm for Rust Shaker and at 1:30pm for Sweat Shaker. Lunch is included for all racers and non-racers can partake by making a small donation.
