Robles Tour

Presented by Hydro Flask

The Robles Tour is a 20-mile off-road tour that traverses a variety of terrain over a unique course designed for both MTB and gravel bike enthusiasts alike. Take in the scenic vistas of the historic Fort Ord National Monument while you ride at a comfortable pace or turn up the heat and push yourself to the limit. This is an untimed recreational ride for all ages and abilities of cyclists, including eBikes. 

All participants receive a 4-day festival pass, complimentary parking, a celebratory lunch after the ride and a commemorative finisher’s medal. A post-ride shower trailer is available and riders will also receive a ticket for one adult beverage at the Sierra Nevada Beer Garden.

Arriving at the Venue 

Whether you plan to arrive at Sea Otter via car, bike or public transportation, you should review the directions to the venue before you set out. Many roads surrounding Laguna Seca will be closed to traffic during the event so you should plan your route in advance and allow ample time when you arrive at Sea Otter to get to your destination. Gran Fondo routes start at the Tire Bridge and finish in the Raceway Paddock.


You must register at least one day before your scheduled event.


No refunds, transfers, or rollovers of ride registration.
