The Mammoth Gran Fondo was chosen as a "top-ten century" bike ride by Bicycling Magazine for its "jaw-dropping vistas".

75% of the Gran Fondo route closed to through traffic.

Other highlights include: all three distances are timed, each participant received a finisher's gift, 6 feed zones, SAG/Tech support, free event photos, a post-ride party with food, beer and live music in The Village at Mammoth.
