TMR races are put on by Trail Monsters, for anyone who loves running on dirt. We keep the fields small on purpose. The trails are what they are — rocky, rooty, occasionally muddy, always honest. Aid stations are staffed by volunteers who actually know what you’re going through!
Our race calendar runs from winter snowshoe events to a badass summer trail series. Every race directly funds our trail maintenance work at Bradbury Mountain.

Want to help?
Our races run entirely on volunteers. Aid stations, course marking, registration, finish-line support, cleanup — pick a shift and see how a small race really comes together. Volunteer at one of our races this year and you’re welcome at any TMR event next year, no questions asked.
