National Events Calendar. This new feature will strive to be a comprehensive listing of events all over the country. Powered by Google Calendar, it is easy to view and use and will continue to be expanded. The next addition will be the creation of Road, Mountain Bike, and Track specific calendars and also a way for event directors to add their events to the calendar regardless of whether they are using SBO for online registration. The link to the National Events Calendar can be found in two places on the site. a. The first is in the Find an Event section in the upper right corner red box b. The second is in the Community section on the bottom of the main page.
