2017  RESULTS are LIVE

 This August 5th, run your first ultra – or your fastest – with us in the beautiful Oakland hills in the oldest continuously running 50k in the US!


Part of the USATF Grand Prix, Skyline 50k offers a scenic and moderately hilly figure 8 course on dirt trails through East Bay Regional Parks, from Lake Chabot Marina to Skyline Gate and returning along much of the Skyline National Recreation Trail. Invite your friends and family to join you and celebrate at the now famous post-race BBQ on the expansive lawn at Chabot.

Great for Rookies

Many a great ultrarunning career has begun at Skyline 50k. The rolling course, great support, and cool August mornings make for a perfect first 50k. In 2017, we are offering a 16-week training program just for first-timers in partnership with Sports Basement. Learn more!

  • 50K Ultra Course

    The Skyline course is an in-depth journey through the southern half of the East Bay hills and travels on much of the famous Bay Area Ridge Trail before it meanders back to Lake Chabot. Runners will be treated to an early morning navigation around the west side of the lake, witnessing the day coming to life on the water, and ultimately return via the east side of the lake to complete the circle. In the interim, runners will travel through grasslands, bay and oak forests, ridgeline fire roads, windy single track trails, towering Redwood forests, and more while taking in all that the diverse Bay Area ecosystems have to offer.

    NEW FOR 2017:

    We heard how much you liked the 2016 course! Last year many of you told us how much you liked going out across the Red Tail trail. You also loved the Stream Trail in Redwood Regional Park. The 2017 course keeps all of those highlights. NEW this year, because of a revision to Park policy, unfortunately, we will no longer be running down Cascade and Columbine Trails. And because of the dam closure, we can not return along the West Shore Trail. So! The race will return down Live Oak and along the East Shore Trail.

Awards, Drop bags, Time limit


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.


We support drop bags at the Skyline Gate Aid Station, located about halfway through the race at mile 14.4. Bring your bag to the start on the morning of the race and we'll transport it to the aid station in time for your arrival. Bags will be returned to the finish after the aid station closes. Please be sure to clearly identify your name and number on your bag.


The time limit is 9 hours. Contact us for early start options if you think you may need more time.

Frequently Asked Questions

Is there a pre-race packet pickup?

Yes! We will have packet pickup from 12-4 at Transports on College Avenue in Oakland.

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.
