A Southern Maine trail running community
It's not about how fast you run. It's about running with heart.
Group runs, fat-ass events, and races at Bradbury Mountain — in every condition Mother Nature ships north.

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.
