About 100 ⨉ 1 Mile Co-Ed World Record Attempt & Running Festival

Let's take on the world record, SF!

Apply to join the 100 ⨉ 1 relay team. The final 100 athletes will be selected in October 2026.

What is the 100x1?

This is the ultimate team endurance challenge: 100 runners, each covering one all-out mile, passing a baton from teammate to teammate until the team completes 100 miles. It blends individual speed with collective grit, where every runner plays an equal role in chasing one finish line.

Training for the 100 ⨉ 1 Mile Starts September 2nd

Come get faster with Shannon Rowbury and Bolota Asmerom! Wednesday track nights at Kezar Stadium or Laney College, and Sunday long runs rotating between our Bay Area retail partners. You do not need to be selected for the final 100 to train with us.
