Rucking is offered for 2025 and involves walking with a weighted backpack. The half marathon early start is available only to half marathon participants; early starters receive a chip time but are not eligible for age group or series awards. Age group awards are given in 5-year increments (starting 0-14) and overall male and female winners receive custom awards. Every participant receives a magnet finisher "woodle."

Course and logistics

Courses are primarily wood-chipped trails with a small portion of grass and more than 60% tree shade. Distances are approximate for trail running: the 5K is listed as 3.21 miles (one inside lap), the 10K as 6.42 miles (two inside laps), and the half marathon as 13.03 miles (two outside laps, one inside lap). Turns are marked with 12x12 turn arrows, 3-foot tall signs, and orange cones. There is one aid station on course that participants pass twice per lap; it will be stocked with water and sports drinks. This is a cupless event; participants should bring a reusable cup or hydration vest. Race shirts are gender-specific dry-wick and are guaranteed for registrations completed by the shirt cutoff; female shirts run small. Parking requires a county park day pass or annual pass that must be purchased online before the event. Volunteers receive a free entry to a future race.
