We run the bay at sea level and the Sierra at 6,000 feet. Every pace, every body and every first mile is welcome.
"Kaia" comes from the sea and "Sierra" from the mountains. We run along the Pacific edge of San Francisco and in the high country around Lake Tahoe. You don't need a qualifying time, a fancy watch or a fee. Show up, say hi and run at whatever pace feels good that day.
Our SF crew runs the waterfront, the Presidio and Golden Gate Park. Our Tahoe crew takes on lakeside paths and Sierra singletrack. Plenty of members run with both.
Flat, fast and salty. Crissy Field into a headwind, beach miles at Ocean Beach, and the climb up to the Golden Gate Bridge you'll come to love.
Thin air, big views. Easy lakeside miles for acclimating, plus pine-shaded singletrack for anyone who wants to climb.
July 24–25, 2027 is the race's 50th anniversary weekend. Pick a distance and we'll see you at the start. Club members run together, cheer together and meet up together afterwards.
Start times and places are from the published race schedule and may change. Check them and register at thesfmarathon.com. Sierra Kaia isn't affiliated with The San Francisco Marathon. We just love running it.
