Staying mostly on the Dr. Paul Dudley White Bike Path, one lap of this marathon clocks in at just over 2.6 miles. By completing a lap, you will have completed a “mini-thon”—a tenth of a marathon.

Beginning at Herter Park, the lap route follows the Charles River and crosses the river at the Eliot Bridge. The loop then continues down along Greenough Blvd, where it eventually crosses the river again at the Arsenal Street Bridge. Finally, the course follows the Charles River back to Herter Park.

The route will be marked with flags and signs.
