Take the SF/LA Challenge

The San Francisco Marathon is happy to announce that we’re partnering up with the Los Angeles Marathon presented by ASICS to continue the SF/LA Challenge!

The SF/LA Challenge medal is an extra medal bringing together two of the best races in California: the San Francisco Marathon and the Los Angeles Marathon!

How does it work? Any runner who completed any in-person distance of the 2025 LA Marathon race can earn the special medal by completing a race at The San Francisco Marathon (July 26-27, 2025).

*If you already qualified at the 2025 LA Marathon, your challenge is starting again!

*All in-person distances qualify excluding the Family 1K or Virtual.

* Check your Bib for the SF/LA Challenge stamp, this is your ticket to pick up your medal at the Expo. If your bib is not stamped, please visit the Solutions Table.

* Medals must be picked up at the challenge tables at the Expo (or Finish Line Festival in the Embarcadero for those with Bib Delivery).

*Medals will not be mailed for any reason.
