We are honored to be recognized by the Gran Fondo Guide as one of the top ten Gran Fondos in North America….for the second year in a row!

A huge “thank you” to our staff, volunteers, sponsors, partners, and all the riders that join us every year for this epic ride in the Eastern Sierra.

Take the challenge this summer and ride two of California's most spectacular bike rides - The Tour de Big Bear & Mammoth Gran Fondo!

The California Pass Challenge is a package deal that includes your registration for the Tour de Big Bear in August and Mammoth Gran Fondo in September. Participants who conquer both rides will receive an exclusive California Pass Challenge cycling jersey and unique race plates.
