About
On the Run Half Marathon is held in Old Orchard Beach, Maine, on March 20, 2027. The event runs a single distance, the half marathon (13.1 miles), with the start at 9:00 a.m. A one-format race means the whole field is on the same course at the same time, and the mid-morning gun gives you room to travel in that morning if you are coming from elsewhere in New England.
A March half in Maine sits well as an early-season target or as a checkpoint on the way to a spring marathon. Build toward it with a 12- to 14-week block: one long run each weekend rising toward 11 or 12 miles, one weekly tempo of three to five miles at half-marathon effort, and easy running the rest of the time. Pace the first three miles slower than feels natural, then settle in. Dress for the start knowing you will warm up considerably by mile three.
