There are several other races taking place both Saturday, July 22, and Sunday, July 23, including half marathons, 10K races and 5K races, as well as a family-friendly run and a dog-friendly race. And if that’s not enough, you can run an ultramarathon this weekend in San Francisco too. Jump to more information about the races taking place around the SF Marathon this weekend and how to register.

What will the weather be like in San Francisco this weekend for the marathon?

Check the weather forecast again before you head out, but the National Weather Service predicts a sunny high of 74 degrees in San Francisco on Saturday and a 70 degrees on Sunday.

Whether you’re planning to participate in a race or just spectate, be sure to drink plenty of water well before going out. You can also be strategic about how to combat heat by cooling your body’s pulse points such as your neck, inside your elbows, and behind your knees. It can bring quick relief. KQED has a thorough guide on how to stay safe during a heat wave.

The full marathon has 14 hydration stations, which include water, GU electrolytes, refill stations, medical assistance, and toilets. You can check out the locations on the SF marathon route map (PDF). The SF Marathon encourages runners to bring refillable water bottles that are 50 gallons or less.

What routes within San Francisco will be closed to cars and public transit?

There will be no changes to BART routes this weekend, said Bay Area Rapid Transit media relations to KQED in an email. However, if you are trying to get to the race for the full marathon’s 5:15 a.m. start time on Sunday, BART service does not start early enough to get you there. Instead, the SF Marathon will have shuttles from six BART stations to get you to the starter’s line.

The SF Marathon website has a breakdown of which city streets will be closed for races at what time, along with some recommended detours. Vehicle traffic on the Golden Gate Bridge, which is on the route, will remain open in both directions throughout the marathon.

A lot of SF Muni lines will be rerouted due to marathon weekend events. Check the SFMTA website for a comprehensive list of rerouted services — SFMTA say the full list of route changes and road closures in San Francisco this weekend for the SF Marathon and other races will be posted to SFMTA’s website soon this week.

Working out closures and timings isn’t super simple, and the SFMTA encourages people to call 311 with any questions about transit.
