Trail Mix Fund
The Trail Mix Fund pays the race registration fee for runners who cannot afford it or are not sure they belong in the sport. It aims to improve diversity in trail racing and remove a potential barrier for under-served and under-represented runners.
Waiving the registration fee alone will not solve this problem, but it may help some. Terrain Trail Runners-STL's partnership with the Trail Mix Fund began in December 2025.
Sustainability
All our races are cup-free. Please bring your own mess kit with a plate and spork for post-race food.
We will not have any paper or plastic cups, plates or utensils at our events, as part of our Zero Waste pledge to reduce waste from our races.
