About the Event

The Tri-Town Loop is a unique, self-guided community run designed to celebrate the historic beauty and architectural character of the neighborhoods we serve. Unlike a traditional race, this is a "run-on-your-own" challenge that lets you explore the scenic residential corridors of Belmont, Arlington, and Newton at your own pace.

The Route: We’ve mapped out a premier 5K course that bridges the gap between our local communities.

Start: Begin your run at the historic Beaver Brook Reservation in Belmont Hill.
The Bridge: Follow the route as it skirts the western edge of Arlington Heights, passing through the quiet, tree-lined streets of the Waverley area.
Finish: Complete your 3.1-mile journey at the Newton Centre Playground, right in the heart of one of Newton’s most vibrant villages.
How to Participate:

Register: Sign up here to join the community leaderboard.
Run: Complete the loop anytime during "Race Week" February 16th through 21st.
Submit: Upload your time and a "Finish Line Photo" from Newton Centre to our results page!

We believe our neighborhoods are best seen on foot, where you can truly appreciate the craftsmanship of a well-maintained home. See you on the loop!
