Coming Feb. 17, 2013. A San Francisco tradition? Not quite, but it is on its way to being there. With the largest Chinatown in the US, it was just a matter of time before someone, in this case the YMCA of San Francisco, thought to create these 5K and 10K Chinese New Year Runs. Thankfully, the course has some short hills but is mostly flat. And while it’s not just for women, it’s definitely a not-to-be-missed event.
