Triple Crown 10K Night Trail Run Series: Lighting Up the Trails in 2025

Welcome to the inaugural Triple Crown 10K Night Trail Run Series—where Friday nights are no longer for early bedtimes, but for headlamps, grit, and unforgettable miles under the stars.

Terrain Trail Runners-STL isn’t just St. Louis’s leading trail and ultra-running group—we’re the heartbeat behind some of the region’s most innovative and inclusive trail events. The TC10K Series is our newest grassroots addition, designed to transform ordinary nights into extraordinary adventures.

Why TC10K Is Different

St. Louis has no shortage of 10K events, both road and trail. But TC10K stands apart for three reasons:

• Nighttime Challenge: Running trails in the dark demand's focus, courage, and a good headlamp.
• Progressive Elevation: Each race increases in climbing difficulty, offering a true test of endurance.
• Trail Diversity: From beginner-friendly paths to technical terrain like the legendary Chubb Trail, runners get a full tour of STL’s premium trail offerings.

Race 1: Bluff View Shuffle 10K

Location: Bluff View Park, Wildwood, MO
Elevation: ~100 ft/mile
Terrain: Flowing singletrack, rolling hills, rocks and roots
​
Runners: 29 participants, many experiencing night trail running for the first time
Bluff View kicked off the series with a gentle introduction to night running. Easy peasy? Maybe. But the thrill of navigating trails by headlamp made it anything but ordinary.

Race 2: Eagle Valley Scramble 10K

Location: Greensfelder County Park, Wildwood, MO
Elevation: ~130 ft/mile
Terrain: Rolling hills, flow trails, steep climbs, loose rock

Runners: 23 participants. Eagle Valley turned up the heat—literally and figuratively. Pierre Antoine Mathieus clocked the fastest men's time of the series at 00:50:57. Young guns Noah Jester (16) crushed the course in 00:57:18, while Andrew Huff (14) bravely tackled his first night trail race, finishing strong in 1:40:15.

Race 3: Chubb Crawl 10

Location: Chubb Trail, Eureka, MO 
Elevation: ~200 ft/mile
Terrain: Steep climbs, technical trails, relentless grind

Runners: 26 participants. With cooler August temps, Chubb Crawl delivered the most technical challenge of the series. Claire Henry claimed the fastest women’s time across all three races with a fierce 1:07:21.

Series Standings & Highlight

Out of 19 series participants, 12 completed all three races—a testament to their dedication and grit.

 Looking Ahead

​Our vision for TC10K is simple: to introduce more runners to the mystique and magic of nighttime trail running. We want to see more boots on the trails after hours, more headlamps bobbing through the woods, and more runners—especially youth—stepping out of their comfort zones.
As we grow, we’re committed to keeping the series grassroots and community-driven. Whether you're a seasoned trail veteran or a curious newcomer, TC10K invites you to light up the night and chase the thrill.

Triple Crown 10K Night Trail Run Series will return in August 2026!
