Waterville Marathon - Full/Half/10K/5K - Running Festival 2026

The Waterville Marathon Running Festival starts and finishes at Thomas College in Waterville, Maine, offering four race options: a full marathon, half marathon, 10K, and 5K. The event accommodates various runners, whether they aim for a 26.2-mile marathon, a 13.1-mile half, or a shorter road race. Pine Tree Racing Services provides timing, and the absence of a time limit makes the longer distances accessible for walkers and slower runners. The courses follow Route 104, venturing into the countryside near Waterville, Sidney, and Oakland before returning to Thomas College. Runners may leave personal bottles at the start-area operations tent, and these will be placed on a designated table at water stations. Maine Endurance Sports Alliance, a 501(c)(3) nonprofit, organizes the event, which is undergoing USATF sanctioning and Boston certification. The festival also links to regional challenge medals, such as Run the Moose, Run the Highlands, and the Vacationland Triple Crown for participants completing specific race combinations.
