Park City is a ski town, but in the summer it turns into a great spot for mountain biking. There are more than 350 miles of trails for non-motorized use that want to be explored on fat tires.
I rode the IMBA Epic loop that combines various trails of Park City and neighbouring resorts. It is over 26 miles (45 km) and you accumulate more than 3,600 feet (1250 m) of elevation gain. Perhaps, my breakfast wasn’t big enough… my energy level was fairly low after the initial climb. That climb after the start winds up through birch forests and lifts you up to an altitude of 3000 meters and makes your lungs and legs burn. After the long climb you ride along the ridge with some ascents and descents until the downhill part of the ride starts.
As short ride before breakfast I went up the Spiro Trail and down the Crescent Mine Grade. The ride was short (7 km), but fun, because the Crescent becomes a sort of giant slalom in the lower section.
