Penn Cycle Puoli Fat Tire Loppet – 18K


Sunday – 12:30 p.m.

The Penn Cycle Puoli Fat Tire Loppet provides a once-a-year chance to ride your fat tire bike on the groomed Loppet Trail. Fat Tire bikes are otherwise not allowed on the snow covered, groomed trail system and mountain bikes or other non-fat tire bikes are never allowed.

Fat tire biking on the MPRB ski trails is not permitted at any other time during the winter.


Can I use any bike?

No. Because the Loppet trail is a ski trail first, and fat tire bikes do less “damage” to the trails, only truly fat tire bikes are allowed. Fat tire bikes are defined as bikes with 3.7” tires or more and less than 10 psi tire pressure.

Like the Marathon Fat Tire event, the course starts at Wirth Park and finishes at Loppet Village near Bde Maka Ska, but the Puoli course skips some of the toughest riding in between and is only 18K long.

The Puoli Fat Tire Loppet generally follows the “red” course – with one deviation. Fat Tire bikes are not allowed in the Eloise Butler quadrant of Wirth Park. Thus, when bikers arrive at Glenwood Avenue (first road crossing), bikers turn to the right onto Glenwood Avenue and pick up a short singletrack section starting at Wirth Parkway and Glenwood before re-joining the ski course. There will be signage and course marshals to direct bikers, but bikers are responsible for knowing the course.
