The Bay to Breakers is THE iconic race of San Francisco. With all of the energy and revelry the race has gotten so big that there are plenty of downsides. The corrals at the start are huge (watch out for the flying tortillas) and difficult to navigate (good luck finding your friends) and the course is filled with drunk kids and looky-loos who have little regard for runners. Navigating around walkers or slow runners who selected the wrong wave is a sure way to sprain your ankle.
Of course - we all overlook the downside to enjoy the kooky costumes, the great music and the energy of the run. Long live the Bay to Breakers. Bring back the centipedes!
