We have a cool real time map of RunSignup activity on our website. Blue dots are the city that a race is in where some user on the Internet is checking out that race’s webpage. Yellow dots are when someone signs up for a race – we use their zipcode since we know it at checkout. Bigger yellow dots mean more people register. We use the cool RedLine13 ZipCode Map to do this neat trick.
Anyway, when the Philly 10K opened up the other evening, Jordan took this video with his cell phone. Pretty fun to watch.
