Knobby tires are out, barriers are being leapt and we're enjoying hourlong conversations about tire pressure. That can mean only one thing: It's cyclocross season. We're proud to kick off the Chicago Cyclocross Cup season with Jackson Park Cyclocross on Sunday, Sept. 20. To streamline registration and help with accurate results, we encourage all racers to pre-register online.
