About This Race
The Skunk Ape 806/314 offers a unique twist on traditional ultramarathons with its time-based format and alternating loop design. Runners can choose between covering as much distance as possible in 8 hours 6 minutes (806 challenge) or 3 hours 14 minutes (314 challenge) on a 2.25-mile loop through the woods of Lowell Park in Dixon, Illinois. The course alternates direction each lap, running forward on odd-numbered laps and reverse on even-numbered laps, creating a mental challenge that complements the physical demands. What sets this race apart is its community-focused atmosphere and exceptional aid station support. The start/finish area serves as the sole aid station, featuring an impressive spread that has included grilled cheese, hot dogs, burgers, donuts, pancakes, and even a chocolate fountain. This creates a festival-like environment where runners can refuel and socialize between laps. The race tracks progress with traditional pen-and-paper methods, requiring runners to check in with volunteers after each lap. With 166 feet of elevation gain per 2.25-mile loop, the course provides consistent but manageable climbing throughout the event. The single track trails wind through wooded terrain with occasional paved road crossings, offering a mix of technical trail running and brief recovery sections. The alternating direction format keeps the experience fresh and prevents the monotony often associated with loop courses.
The course consists of a 2.25-mile loop through Lowell Park's wooded single track trails. Each lap features 166 feet of elevation gain with a few paved road crossings breaking up the forest sections. The unique aspect is the alternating direction format - runners complete the first lap forward, second lap in reverse, third lap forward, and so on throughout their time limit.
The single aid station is located at the start/finish area, requiring runners to return to this central hub after each completed loop. Volunteers track progress manually, and runners must confirm their lap completion before continuing. The wooded terrain provides natural shade and technical trail features while remaining accessible to runners of varying experience levels.
