One of the most iconic running events in the United States is seeing a major resurgence.

The legendary Bay to Breakers in San Francisco is expecting more than 30,000 participants in 2026, continuing a strong growth trend over the past three years. Participation has reportedly increased around 20% year-over-year, reflecting renewed momentum not only for the event but for running culture in general.

For race directors across the country, there are a few interesting takeaways from what’s happening with this historic race.

First run in 1912, Bay to Breakers was originally created as a way to help lift the city’s spirits after the devastating 1906 San Francisco earthquake. Over time, it became one of the most unique running events in the country.

The race runs 7.46 miles (12K) across the city—from the San Francisco Bay to the Pacific Ocean—passing through neighborhoods and landmarks before finishing at Ocean Beach.

But what really sets the event apart is its culture. While elite runners compete at the front, the majority of participants show up in costumes or creative group themes, turning the race into a citywide celebration.

One of the biggest drivers behind the race’s recent growth has been the expansion of its Corporate Teams Program.

For race directors, it’s a reminder that the right mix of community, creativity, and partnerships can keep an event thriving for generations.
