Endurance Grid lists 3 obstacle course races in Maine, from July to October 2027 across 1 city.
The obstacle course race calendar in Maine is busiest in July and October.
Obstacle course races (OCR) combine running over varied terrain with a series of physical obstacles — walls, rope climbs, monkey bars, carries, and crawls. Courses range from a 5K with under 20 obstacles up through 10Ks, half-marathons, and beyond, depending on the organizer and race series.
The barrier to entry is lower than it looks. Most events run open heats designed so beginners can finish — with help on the obstacles when they need it, and strangers often boosting each other over the walls.
