Boston Double: Elite Runners Conquer 52.4 Miles Twice

The "Boston Double," a challenging 52.4-mile ultramarathon, saw seven runners from the Trail Animals Running Club undertake a unique endurance test. These athletes began their journey before dawn, running from Boston's finish line towards Hopkinton, only to then join the official Boston Marathon.

This grueling "Double Boston" or "Boston Yo Yo" has been a lesser-known tradition for at least three decades, attracting individuals drawn to extreme endurance sports. Participants like Justin Hetherington, who ran over 500 miles in January for preparation, emphasized the mental fortitude required. The group gathered at 3 a.m. on Boylston Street, their distinct bibs signifying their dual challenge.

Support crews and aid stations, including stops at Dunkin', aided the runners. Kathryn Zioto described the experience as a mental game, especially on the return leg to Boston. Participants like Brendan Morgan and David Desnoyers noted the electric atmosphere and the profound camaraderie among those pushing their limits. Morgan, who ran 80-plus miles weekly for six weeks, called the experience "magical."
