The SF Stair Challenge

5 miles. 2,000 steps. 100% pure fun!

Are you up for the challenge?

Take on a one-of-a-kind, scenic physical challenge connecting some of San Francisco’s best stairways into one epic route!

Save the date for Saturday, May 8, 2027. Tickets will go on sale early March, with early-bird access and pricing for Walk SF members!

Walk SF held the fourth SF Stair Challenge on May 2, 2026, exploring the incredible stairways of Pacific Heights and USF Lone Mountain. It was the biggest and best yet, bringing out hundreds of stair-climbers. (For a recap and photos, check out our blog post.) The 5th annual SF Stair Challenge will be on Saturday, May 8, 2027. Tickets will go on sale in early March. The super secret route will be crafted again by our mastermind team of WalkLab volunteers and include magnificent views and hidden gems, coming in around 5 miles with about 2,000 stair steps. All proceeds from the SF Stair Challenge support Walk SF’s work making San Francisco the safest, most pedestrian-friendly city in the United States.

Wishing you had the routes?

We get it! The routes are awesome. We’re sorry to say that only SF Stair Challenge ticket holders have the routes. But as a Walk SF member, you’ll get curated, do-it-yourself walks every few months in your inbox – plus early bird access and discounts to the SF Stair Challenge and our other marquee walking event, Peak2Peak. We also regularly share walk ideas in our newsletter. So if you love walking, join our community!

Thank you to our generous event sponsors of the 2026 SF Stair Challenge!
