‘Whack Jobs’ Film Reveals Fat-Bike Obsession in Michigan U.P.

Fat tread on fresh snow has a cult following around the world. But on Michigan’s U.P., in and around the Lake Superior town of Marquette, the obsession is strong.

So is the infrastructure. Each winter, the area’s legion fat-bikers depend on a small group of snow groomers to compact and tamp singletrack to a perfect consistency.

The result is a winter wonderland, a network of groomed fat-biking trails unlike any other place.

Snowy singletrack winds from downtown Marquette up into the hills, past old mining equipment, and even through chainsawed ice tunnels that form below massive, seeping pipes (see photo below).

It’s a strange and wondrous experience, and the new film Whack Jobs profiles the personalities (and trail-grooming technologies) fostering a winter trail network that, according to producer Aaron Peterson, “has become an example for the world.”

Overall, there are three trail networks and about 60 miles of groomed trails in Marquette County. Travel Marquette worked with Peterson to produce the film.
