Millinocket Marathon & Half
SEA TO SUMMIT RACE SERIES

Race Series Overview

Millinocket could not RUN without the support of Run MDI!

Did you know that race director Gary Allen founded both the MDI Marathon and the FREE Millinocket Marathon? The same core team produces and manages both events, volunteering their time for Millinocket, which is made possible by the successes of the award-winning MDI races!

The Maine Sea to Summit Race Series is a celebration of the kinship felt between these two magnificent events. Both MDI and Millinocket feature USATF certified marathon and half-marathon courses that may be used to qualify for entry into the Boston Marathon and NYC Marathon.

All Sea to Summit entrants will earn an extra special commemorative medal to be picked up in Millinocket.

Participants may select any distance option offered at either race.

We hope you’ll go all the way by signing up for the Sea to Summit Race Series today!
