Running since 1982, Skyline is one of the oldest continuously running 50k races in the United States. The course starts and finishes at Lake Chabot Marina and travels a large loop through the East Bay Regional Parks, taking you all the way to Skyline Gate.

Skyline is known as a great race for first-timers. Each year we enjoy incredible aid station support from great Bay Area running groups like the Dusty Bottoms, Running for a Better Oakland, Lake Merritt Joggers and Striders, Pamakids and more. On course, the Volunteer Safety Patrol appears like a flash mob at key intersections to provide you direction and good cheer.

This support means that Skyline is super fun no matter where you are in the pack. For front runners, this is a fast competitive race. For former or aspiring front runners, it means Skyline is a great day you’ll think about all year. Either way, it all ends back at Chabot Marina where in years past, we have stuffed you with BBQ and beer.
