Bike racing is one of the most popular and exhilirating sports in the world. Most countries divide racers up by level of experience, so if you're a beginer, don't worry about getting crushed by the competition. In your first race, stay near the front of the field, but don't break the wind for other riders. Try to stay tucked behind someone else so they break the wind for you. For safety, ride in as straight a line as possble and avoid swerving. Observe more experienced riders in your race, and emulate what they do.
