The Inaugural Forest Five K and HALF Marathon. Bring it! Run the FOREST FIVE K on the same off-road course that triathletes and duathletes use enjoy the beauty and challenge of Bass River State Forest. A perfect race for you whether you’re looking for cross country PR or just there for fun. The FOREST HALF Marathon is on a marked course that is mostly paved roads throughout the Bass River State Forest Campground. Even better, a great way to participate for family and friends to the triathletes and duathletes participating on Saturday or Sunday. It’s a great way to start the season!
