ABout TMR
A Trail Monster is someone who needs to run trails — not the people who show up only when it's not too muddy.
We’re a group of trail runners based in Southern Maine who share a passion for the outdoors. We host weekly group runs, organize races each year, and put in hours of trail maintenance at Bradbury Mountain.
Anyone with a serious interest in trail running is welcome on a group run. Becoming a Trail Monster takes more than that.
Get Involved
Three ways in
Join a group run
Weekly runs across Southern Maine. All paces welcome — show up and run.

TMR swag is available for members only. But be on the lookout for other race merch, which is available to anyone who is involved in a race, not just TMR members!
