Detroit

Detroit's running and cycling scenes revolve around Belle Isle, the 982-acre island park in the Detroit River where the flat Ronde Belle Isle cycling circuit (26.6km) draws riders year-round. The metro area extends into Huron National Forest and state parks to the north where mountain bikers tackle technical terrain—Shelden's BIG Bang XC MTB Race (40.2km) is the regional benchmark—while distance runners mostly stick to city parks and the Detroit River Walk for flat, urban mileage.
