Race Info

Tunnel Marathon & Half Marathon

Fast. Scenic. Boston Built.

The Tunnel Marathon and Half Marathon races offer some of the fastest courses in the country. These net-downhill courses deliver outstanding times thanks to their steady grade and low starting elevation. It’s the ideal race to set a Personal Record, earn a Boston Qualification (marathon), or run your first marathon or half.
