Penn Cycle Fat Tire Loppet 35K


Sunday – Noon

The 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.

The Penn Cycle Fat Tire Loppet is part of the Great Lakes FAT BIKE Series.

Fat tire biking on the Loppet Trail system 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 4” tires or more and less than 10 psi tire pressure.

The Fat Tire Loppet starts at noon on Sunday – after the skiers have passed through the park. Bikers will start at Wirth Park, then bike the entire trail system to the Loppet Village in Uptown, skipping only a short golf course section.
