Whether you're new to racing or just looking to hone your skills, the Early Bird Training Series is a great place to start. Even though it won't cover everything, it will cover a lot of ground, including cornering, line choices for turns, riding in a pack, riding next to others, paceline workouts, drafting, and a lot more.
