About the Event

Maine Endurance Sports Alliance (MESA) a 501(c)3 nonprofit is proud to continue the great running history established by The Great Waterville Marathon & Half with the introduction of the WATERVILLE MARATHON – Full/Half/10K/5K – Running Festival on Sunday October 4, 2026 (NEW DATE) starting at 7:00 am at Thomas College in Waterville Maine allowing more participants of all abilities to cross the finish line. This event is in the process of being USATF sanctioned, and Boston certified. All courses start at Thomas College, travel along Rt 104 into the beautiful countryside of Waterville, Sydney and Oakland Maine and back to Thomas College. (course maps can be found on our website).

We have already secured Pine Tree Racing Services to be the official timer for the race. There is NO TIME LIMIT - we want you to reach your goal to complete the race.

For participants who have "BOTTLES", we will accept "BOTTLES" at the operations tent at the starting line until 6:00 am. These will be on a special table at each water station for the participants to pick up.

We will have a vendor area at the finish line for participants and their guests. There is plenty of nearby parking, affordable lodging and dining to make this a destination for the whole family.

More information can be found on our website www.mesa-maine.org or on our Facebook page Maine Endurance Sports Alliance. Packet pickup will be October 3, 2026, from 3-6 pm at THE MAINE EXPERIENCE close to the starting line and the morning of the race at the registration tent.
