102nd Annual Bay to Breakers
This outrageously costumed affair is a San Francisco tradition, and kids will love the bright colored costumes and centipedes: groups of registered racers in a themed, connected costume. Parents with kids should aim to start on the earlier side, as the crowd can get more raucous as day wears on. And be in the know: this is San Francisco so there is a 99% chance there will be at least one nude runner. If being in the race feels too hectic for your little ones, find a spot along the route and watch for bunnies, unicorns, life-sized crayons, and lots of balloons.  Costumes encouraged. Sun., 7 a.m. – 12 p.m. San Francisco. Race registration is $59/adult; 29.50/child; children 2 and under are free. All Ages. Event details.
