Wildwood Trail Marathon is now part of the Trail Mix Fund!
In an effort to improve diversity in trail racing and remove a potential barrier for the under-served and under-represented, the Trail Mix Fund pays the race registration fee for runners who cannot afford it or aren’t sure they belong in the sport.
We also believe that there are more BIPOC & LGBTQ+ people who would like to race and would enjoy being part of the community but aren’t comfortable taking that step of signing up to race. Waiving the registration fee alone won’t solve this problem, but maybe it can help some.
Terrain Trail Runners-STL's partnership with the Trail Mix Fund began in December 2025, and we hope you'll consider donating or applying!

MARATHON COURSE DESCRIPTION
The Wildwood Trail Marathon starts on the asphalt Hamilton-Carr Trail which takes runners to the chat surfaced Al Foster Memorial Trail. The Al Foster Memorial Trail will take marathoners to the Bluff View Trail, where they will climb to the bluff that gives the trail its name!
After leaving the first aid station on the course, runners will proceed back down the Bluff View Trail and spend a number of gorgeous miles doing the entire Rock Hollow Trail. Racers will then leave the Rock Hollow Trail and run the entire length of the Al Foster Memorial Trail to the Sherman Beach Trailhead. From Sherman Beach, runners will take a connector trail to the Cedar Bluff Trail and return to Sherman Beach on the Stinging Nettle Trail. Once reaching Sherman Beach for the last time, competitors will travel on the Al Foster Memorial Trail and Hamilton-Carr Trail to the finish of the Marathon at LaSalle Spring Middle School.
The course is a combination of approximately 2 miles of paved greenway trail, gravel, dirt and 90 percent single track with enough rocks and roots to keep you present with approximate ELEVATION GAIN of 1700ft!
PLEASE NOTE: THIS IS A TRAIL MARATHON AND NOT YOUR ROAD 26.2 SO YOU WILL BE RUNNING 26.2-ISH MILES.
No Wimps, No Whining!

*NEW* TENKAY COURSE DESCRIPTION
The Wildwood Trail F.L.A.T. Out Tenkay begins on the paved Hamilton–Carr Trail, which leads runners to the chat‑surfaced Al Foster Memorial Trail. Once on the Al Foster Memorial Trail, 10K runners continue straight on the crushed‑gravel path, following the Mighty Meramec River to the Sherman Beach Trailhead. After checking in with the aid station at Sherman Beach, runners return along the Al Foster Memorial Trail and Hamilton–Carr Trail to finish the 10K at LaSalle Springs Middle School.
The course is an out‑and‑back route, combining paved and crushed‑gravel surfaces—approximately 3 miles out and 3 miles back. This design makes the course ideal for both runners chasing a fast 10K PR and beginners or kids looking for a friendly, approachable introduction to trail running. The route offers a scenic trail experience without technical terrain, rocks, or roots to navigate.
