The Black Fly Challenge is a classic Adirondack Mountain gravel grinder 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 BFC started as a mountain bike race but is now a top choice for cyclocross racers as well as tandems and even unicycles! The top racers finish the race in about two hours while the rest of the field may take four or more hours.

It is the mission of the Adirondack Mountain Bike Association, producer of the Black Fly Challenge, to promote, maintain and preserve multi-use recreational trails in the West-Central Adirondack region and beyond.

This will be accomplished by:

• Reinvesting race proceeds in our local communities;
• Partnering with like-minded individuals, agencies and organizations;
• Supporting the cycling community and outdoor recreation efforts;
• Coordinating efforts of various stakeholders and where feasible,
• Providing resources in the form of labor, materials and/or donations,
• Having a positive impact on the local economy.
