Yes. Each events specific race page & it's corresponding registration page lists when registration for that event will close. Online registration will close 7 days before event. However, most all of our events sell out before that close date, so it is important to register as early as possible. Prices increase as the day of the event approaches. Each race page has a "Percent Full" icon in the upper right above the red REGISTER button, so watch that and make sure not to delay if you want to race as races do sell out. Also, our splash page has a ticker that announces sell out percents. But once a race sells out, it sells out and you're SOL.
