It always looks like a lot of fun. I haven’t done it but the people doing it look like they’re having a ball. Here’s a pretty good response from ChatGPT that sums it up:
Bay to Breakers is a legendary 12K race in San Francisco, held annually since 1912. It’s known for its fun, party-like atmosphere, with many participants wearing wild costumes—or nothing at all—while running from the Bay (Embarcadero) to the breakers of Ocean Beach.
