The 50K gravel route explores some of the greatest hits in our wonderful East Bay Regional parks. The first half of the day will be similar to the 100K course, taking you through Sibley and Tilden parks. Then you will descend the East Ridge trail in Redwood to return to St Marys College for the post-ride meal.

Alternative Car-Free Start

The alternative start in Tilden Park is not available for this route. You must sign in at St Mary's College.
