We are very much looking forward to an in-person Skyline 50k in August! For those of you who are new to the race, 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 often a fast competitive race. For former or aspiring front runners, it means Skyline is a great day you’ll think about all year.

It all ends back at Chabot Marina where in years past, we have stuffed you with BBQ and beer. We hope to again, Covid permitting.


New-ish Half Marathon

It only went slightly noticed in 2020 that there’s now a half marathon as part of Skyline. We will be running the looped course created for the 2020 virtual race. It’s a great course. Never let a good crisis go to waste!

The half is true to the Skyline tradition, as a great challenge for all abilities.


Schwag and Awards

All runners will receive a race shirt, which you can pick up at times we will post at the Golden Squirrel in Oakland. If you want us to mail your shirt to you, we’re happy to. It’s just a little more expensive to cover the cost of postage and packaging.

Because of the nature of this virtual race, there will be no special finisher or age group awards.


USATF Grand Prix and UTMB

Skyline 50k is part of the P-USATF Grand Prix. The race is also worth 2 UTMB points.

Frequently Asked Questions

Is there a pre-race packet pickup?

Yes! We will have packet pickup from 1 - 6pm at The Golden Squirrel at 5940 College Avenue in Oakland on Saturday, August 3.

Is there race-day pickup and registration?

Yes! We usually have bib pickup open at about 5:30am on race day. We always have a few stragglers that like to register on race day too. Race day registration is $115, so save a few bucks and register when everyone else does!

Are there places where my friends and family can crew or watch?

Most of the aid stations are vehicle accessible. For driving directions go to the Aid Stations page under the Course tab.

Are there finisher awards or medals?

While we do offer a hearty congratulations, along with various race swag items, we strive to emphasize the experience over the medals, and thus devote more energy toward the things that will make the race one to remember, including an elaborate post-run bbq and beer extravaganza where you can connect with your fellow finishers. Awards will be given to the top overall male and female, as well as the fastest male and female finishers in each 10-year age group. We also have special awards to be bestowed upon the first male and female rookie ultramarathoners.

Is there a time limit?

Yes, there is an 9-hour time limit. Intermediate cutoffs are located at Skyline Gate (mi 14.4/11:20 am), and Bort Meadow return (mi 23.3/2 pm). There is a 'soft cutoff' at Big Bear (mi 20.2/ 1pm) to ensure runners are on pace. Please remember the cutoffs are in place so the volunteers can join the post-race festivities. If you feel that you may need additional time, please contact us about early start options.

Do you need volunteers?

Our races depend on the generous spirit of the running community to ensure every participant is well supported. Volunteers will receive a free entry to a future Scena Performance event. Please fill out the volunteer form to indicate your interest and we'll get back to you with more information.
