Armstrong Trail
The Armstrong Trail shares a trailhead with Spiro, just north of Park City Mountain Resort (PCMR). This is an uphill-only trail. Commit to the full ride, or don't start uphill. The climbing is sustained but not steep -- most riders won't drop out of the middle chainring. Technically, it's pretty easy by Park City standards, suitable for strong advanced-beginners or conditioned intermediates. The Armstrong Trail is 4 miles long, with 1300 vertical feet elevation change. Top altitude is 8150 feet at the Midmountain Trail just below Iron Mountain. Because Armstrong is one-way, you need to add some trails to complete a ride.
