Relay Cross, a silly but exhilarating way to start the cyclocross season, is back for its 4th edition. Racing will take place in Jackson Park on Sunday, Aug. 25, and pre-registration is now open. Fields will fill quickly, so be sure to have your partner's names and USAC license numbers handy. (For more information about how the race works, read the 2013 technical guide.)
