Fat-tire biking is an awesome way to enjoy miles of winter riding fun in Theodore Wirth Park.
The Loppet Foundation grooms and maintains three singletrack fat-tire biking and snowshoeing trails in North Wirth: Area 36, Conundrum, 45 North.
For the most up to date Loppet trail information and conditions, check out our Trail Locations & Maps page.
Additional Fat Biking trails managed by MORC/MOCA (Minnesota Off Road Cyclists) are available in the park as well. Head to the MORC website or check the “MORC Trails” app for current trail information.
Biking is allowed on paved and plowed bike paths, or on designated mountain bike trails only. Biking is specifically NOT ALLOWED in the Eloise Butler section of trails (sometimes referred to as southeast Wirth), or on any groomed ski trails.
Biking in the winter on the Back 40 and Area 36 trails require ski trail crossings and therefore are limited to true fat bikes. Bikes must have 3.7″ tires or more and less than 10 psi tire pressure.
