Ah, summer. If only you weren’t so short. French Pass, located at 12,046 feet on the Continental Divide just east of Breckenridge, is a marvel of a mountain bike destination. But our window to ride it without traipsing through too much snow is tight. Maybe four months at most. My twin brother Sean and I made the pilgrimage last week during a circumnavigation of Mt. Guyot. It takes your breath away in more ways than one.
