Thunder Chicken 100K Stage Races

Thunder Chicken 100K Stage Races is a three-day trail stage race in Wildwood, Missouri, from April 30 to May 2, 2027, organized by Terrain Trail Runners. The stages build to roughly 100K in total: a 21-mile (33.8 km) on Friday, April 30, a 26-mile (41.8 km) on Saturday, May 1, and a 25K (15.5 miles) on Sunday, May 2. Start times were not published at the time of listing.

Stage racing gives you the total distance of a 100K without asking you to run it in one go, which makes this a good introduction to multi-day events or a way to bank big mileage in a structured setting. You will need to recover overnight between stages, so your 14- to 16-week build should include back-to-back long runs on consecutive days and a focus on fueling, sleep and foot care. Ozark trails are rocky and rolling, so expect constant short climbs and use protective shoes. It suits marathoners moving into trail ultras as much as experienced runners who want a different kind of weekend.
