Skyline 50k Endurance Run

The Skyline 50K Endurance Run is one of California's oldest and most celebrated 50K races, taking place annually in August at Lake Chabot Marina in Castro Valley. This event is designed for both first-time ultrarunners and seasoned veterans, featuring a scenic course that loops through the East Bay Regional Parks. Participants benefit from excellent aid station support provided by local running groups and a vibrant atmosphere created by enthusiastic volunteers.

Runners receive a race shirt, special socks, and a finisher's medal, with awards for top performers in various age categories. The event culminates in a festive celebration with plant-based BBQ and beer. Visit the organization's website for the most recent information.
