The Black Fly Challenge is a classic Adirondack Mountain bike race that takes place every year on the second Saturday in June. The race changes direction every year with the start and finish alternating between Indian Lake and Inlet, NY. Over half the 40 mile course traverses the rugged Moose River Recreation Area on mountain roads composed of dirt, gravel, sand and exposed boulders with several steep elevation changes. The top racers finish the race in about two hours while the rest of the field may take four or more hours. Live music, food and more at the finish! Race has an entry fee, free to watch.
