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!
