Maine runs a year-round race calendar, so there’s almost always a race near you. The calendar is busiest in October, November, and June, with races most often held in Portland, Kennebunk, and Biddeford.
Races in Maine follow a rocky, island-studded Atlantic coastline in the south and east, with dense forest, lakes, and the Appalachian high country around Mount Katahdin to the north. Expect coastal road races near the water and forested trail runs with real climbing inland.
Conditions vary widely by region across Maine, so weather lives where it’s accurate — each race page shows its typical race-day high, low, and rain chance from NOAA climate normals for that venue and date.
