Donny's Dash

Donny's Dash is held in the scenic town of Simsbury, Connecticut, on October 31, 2026, with a 5K starting at 9:30 a.m. The event is organized by the Hartford Marathon Foundation, suits runners of all levels, and makes an easy outing for families and groups of friends.

A late-morning start in a Connecticut river town in October usually means crisp air and good footing, close to perfect conditions for a road 5K. If you are using it as a fitness check, warm up for at least ten minutes and aim to run the second half slightly faster than the first. If you are here with family, walking or jogging the 3.1 miles together works just as well; nothing about this distance requires a training plan to enjoy it.
