Grand Canyon Highway from Marble Canyon

Grand Canyon Highway from Marble Canyon covers 78km and 1,601m of climbing, reaching 2,628m at the summit. The average gradient of 2.1% disguises ramps of 6.3% — the kind of gradient that turns plans into prayers. This is a climb of endurance — the kind of effort measured in hours, where pacing matters more than power. The summit at 2,628m sits above the treeline, where the air thins and the views extend to distant peaks. Located in Arizona, United-states.
