Produced by TUFF Ventures, the Mammoth TUFF & BUFF Weekend includes a gravel cycling adventure through the Eastern Sierra from Mammoth Lakes with three distance options. BUFF is a beer run held in Mammoth Lakes Village.
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.
