Triple Crown 10K Night Trail Run Series

Triple Crown 10K Night Trail Run Series is a three-week night trail running series in Wildwood, MO, held on August 7, 14 and 21, 2026. Each event is a 10K race hosted at a different trail system in the St. Louis West County area, organized as a hill progression to emphasize climbing at night with a headlamp.

The individual races in the series are:

• Bluff View Shuffle - 10K with about 100 feet per mile climb
• Eagle Valley Scramble - 10K with about 130 feet per mile climb
• Chubb Crawl - 10K with about 200 feet per mile climb

Online three-race series registration includes a custom cotton/poly short sleeve unisex shirt, a series finisher sticker that features all three races, and a post-race snack and cold beverage. Pick 2 and individual race registrations include a race-specific finisher sticker and a post-race snack and cold beverage. Race day registration is available for individual races for $75 cash only. Swag may be available for purchase at packet pickup for $15 cash only while sizes last.

The event partners with the Trail Mix Fund to cover registration fees for runners who cannot afford them; that partnership began in December 2025. The races follow a cup free policy; participants are asked to bring a plate and spork as part of the event zero waste pledge. Visit the organization's website for the most recent information.
