Running… In the woods!

Welcome to the internet home of the Trail Animals Running Club (TARC). We are the largest trail- and ultrarunning club in the Northeast United States, with our home on the trails of eastern Massachusetts and membership from all around the world. We are an all-volunteer organization that plays host to free group runs and low-cost races, offering distances from 5K to 100 miles and beyond. We welcome runners of all abilities. So whether you’re a first-time trail-runner or a decades-long veteran, come get your feet dirty with us!

Here you can find info about the races we host, the weekly trail runs our members organize, and trails to run in the Boston area. Additionally, you can connect with our community on our Facebook page to catch up on the latest news, ask questions, or connect with other Trail Animals to schedule a run or have them show you around their local trails.
