Black Fly Challenge Adirondack Gravel Grinder

In the heart of the Adirondacks, the Black Fly Challenge Adirondack Gravel Grinder—sponsored by North Country Subaru—returns as one of the region’s most demanding and beloved cycling events.

This 40-mile gravel race runs point-to-point from Inlet to Indian Lake, cutting through the wild terrain of the Moose River Wild Forest. Equal parts grit, scenery, and community, it’s a race that defines Adirondack endurance riding.

A race, not a ride.

Let’s be clear: the Black Fly Challenge (BFC) is not a casual spin through the woods. It is a timed race with a strict five-hour cutoff.

Riders who don’t finish within that window are recorded as DNF, and the sweeper crew—staffed by race officials—has the authority to pull participants from the course.

That edge is part of what makes the event so compelling. The BFC attracts a wide spectrum of riders, from elite gravel racers chasing podium finishes to recreational cyclists testing their limits.

And then there are the outliers—tandem teams, mountain bikers, even the occasional unicyclist—adding a dose of Adirondack eccentricity to the field.

A rugged Adirondack course.

More than half the course winds through the remote and scenic Moose River Wild Forest, offering a true backcountry experience on two wheels. Riders encounter a mix of gravel roads, rugged terrain, and elevation changes that demand both endurance and technical skill.

Because it’s a one-way race, participants must plan transportation carefully. Many bring a friend or arrange for someone to move their vehicle to Indian Lake. Limited shuttle options are available but should be reserved in advance.

After crossing the finish line, riders are greeted with a well-earned celebration—food, drinks, and the shared satisfaction of conquering one of the Adirondacks’ toughest rides.

Why this race stands out in the Adirondacks.

The Black Fly Challenge isn’t just about speed. It’s about immersion. Few events offer such direct access to the Adirondack backcountry, where the landscape feels vast, quiet, and untamed.

It’s also refreshingly unpolished. The race is unsanctioned—no license required—and retains a grassroots feel that reflects the region itself.

The prize purse, however, is anything but modest, with more than $17,000 in payouts and awards drawing serious competitors each year.

For spectators, the event offers a glimpse into a passionate cycling subculture. The finish line at Indian Lake becomes a lively hub, where stories of mechanical mishaps, near misses, and personal victories circulate freely.
