For many participants, what didn't happen at the Bay to Breakers this year mattered more than what did happen: no bombs went off.

The bombings at the Boston Marathon raised fears that copy-cat attackers would target San Francisco's highest-profile footrace.
Race organizers and local authorities beefed up security. The measures included extra surveillance cameras, cops in civilian attire, and restrictions on backpacks. And no terrorists appeared.
That doesn't mean nothing happened.
Ethiopa’s Tolossa Gedefa Fufi crossed the finish line first, and Burundi’s Diane Nukuri-Johnson won the women's division.

One man died: David Hamzeh fell from a roof during a Bay to Breakers party Sunday afternoon, police and hospital officials told Bay City News.
