Mammoth TUFF

Gravel Bike Ride & Beer MileMammoth TUFF is a gravel ride event offering three distances to riders with unforgettable views of the Eastern Sierra, culminating with a party in The Village. Join TUFF Ventures for the Mammoth BUFF beer run on Friday, September 18, Mammoth TUFF gravel ride on Saturday, September 19, and awards and raffle in The Village on Sunday, September 20. 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. The short course will circle the famous caldera. The medium and long courses travel through the Volcanic Tableland formed by the Long Valley Caldera. Prepare to be transported back in time.
