Mammoth Gran Fondo

Cat. 3: Mile 30 and 63

Cat. 4: Mile 6, 13, 39, 74, and 98

The Mammoth Gran Fondo (formerly High Sierra Fall Century) is a scenic ride at altitude, leading around Glass Mountain with views of the Sierra Nevada Range in the west, Mono Lake in the north, and the White Mountain Range in the east. The ride follows a clockwise loop, which is sometimes ridden in reverse direction. It is part of the Mammoth Kamikaze Bike Games, a multi-day celebration of cycling.

The century and timed gran fondo route starts at the Village in Mammoth (shorter routes start at Whitmore Ball Fields). Navigation is simple: a left turn onto Highway 395 (follow for about 20 miles), right turn onto Mono Lake Basin Road (39 miles), right turn onto Benton Crossing Road (31 miles), right turn onto Highway 395 (5 miles), and a final left turn back up to Mammoth Lakes.

Each of the road sections of the loop includes a summit, most with gradual ascents and descents: Deadman Summit on Highway 395, Sage Hen Summit on Mono Lake Basin Road, and Wildrose Summit (steep at the end) as well as Watterson Canyon Summit on Benton Crossing Road. Sage Hen Summit is the highest point at 8,139 feet.
