It took a while for Wellesley to wake up to the earlier-than-usual start time for Monday’s Boston Marathon, but once the crowd got going, participants where given a solid boost as they hit the halfway mark on the 26.2-mile course.

This included a less touch-feely Wellesley Scream Tunnel alongside the closed-off Wellesley College campus, where students emerged in big, loud numbers to cheer on runners along a stretch starting to flex its foliage.

Wellesley’s fastest finisher among 50-plus residents listed by the Boston Athletic Association was Susan Mix, who ran the course in 3:03:31. She was followed by Heather Garni, who finished in 3:13:01.

The fastest male finisher was Richard Dravenstott in 3:17:12. More results.
