Welcome

It's with great, great sadness that we recognize the loss of Ken Gregorich, a great runner and former race director. Join us in dedicating the 2026 race to Ken's memory. Skyline is one of the oldest continuously running 50k races in the United States — and one of the best days of the year. The course starts and finishes at Lake Chabot Marina, winding through a big loop in the East Bay Regional Parks all the way up to Skyline Gate. It's a classic for a reason: beautiful trails, significant climbing, and a finish line that feels genuinely earned. Skyline has a well-earned reputation as the perfect first 50k. The volunteer support here is something special — groups like the Dusty Bottoms, Running for a Better Oakland, Lake Merritt Joggers and Striders, and the Pamakids bring real energy to every aid station. The Volunteer Safety Patrol appears like a flash mob at key intersections, keeping you on course and cheering you on. Whether you're racing for a podium spot or out there to finish strong and have a great day, Skyline delivers. It's fast and competitive at the front, and a genuine celebration everywhere else. Either way, you'll be talking about this one all year. See you at the Marina — and yes, there will be BBQ. Download the Skyline 50k Athlete Guide! Download the Skyline Half Athlete Guide!
