What began as a low-key 5K on the esplanade in Boston has grown to become an international series of track meets featuring the same accessible distance and the same incredible grassroots vibe, with paced races for runners of all abilities in 20 cities across the US, Mexico, Canada and the UK. Whether you’re stepping down in distance from a spring marathon or if track is your focal point this year, these races bring out the best of the running community: competition, camaraderie and fast times.
