Tuff (tŭf) is a general term for all consolidated pyroclastic, volcanic rocks.

Mammoth TUFF is a gravel cycling adventure through the Eastern Sierra from Mammoth Lakes through the TUFF terrain of the Long Valley Caldera.

The name, Mammoth TUFF, is a nod to the Long Valley Caldera and the volcanic stone that defines ‘gravel’ in the area. The caldera was formed about 760,000 years ago in a volcanic eruption from which the magma still underlies it, heating underground water and fueling hot springs the event will ride by.

Prepare to be transported back in time on routes used by miners and even further back.

The short course is around 45 miles with 2,000 feet of climbing and will circle the famous caldera.

The long course is around 100 miles with 8,000 feet of elevation gain and travels through the Volcanic Tableland formed by the Long Valley Caldera.
