More like being in a dream than riding a bike. The trail starts around 10,600' and climbs to 11,300' in the first mile. It's steep but not technical at all. If anything the lack of O2 will make you pay for living low. Swooping single track, breathtaking vistas, exciting exposure, all just amazing stuff.
Words don't describe but this video helps you get the idea. Outside Online posted this just when the winter blues start to set in.
