Great Woods Marathon & 5k

Welcome to the Great Woods Marathon & 2-Mile Test Run! Ready to chase your next PR in a fun, fast, and super supportive setting? Welcome to the Great Woods Marathon, an all-new race experience built for speed, safety, and serious good vibes — all happening at the iconic Great Woods in Mansfield, MA (now known as the Xfinity Center)!

The Course: A flat, fast 2-mile loop, designed for runners who want to stay close to friends, family, bathrooms, and cheers! Start just 0.2 miles ahead of the finish line and complete 13 easy-to-track laps — every mile is marked, every step is supported, and you’re never far from water, music, or motivation.

Just a view from the bike. There are traffic controls on the course for other events at the venue that will not be there the day of the race. 12 minutes, making sure people see all the details. Trust me, the video does not do the comfort of the course justice!

Checkpoints for accurate mile splits

Water stops every 2 miles

Personal hydration tables

Tons of on-site parking
