If you're brand new to bike racing there are a lot of details to learn. We'll do a quick series of posts this week to help new riders coming to the Ann Arbor Spring Training Series or to any other race.
The first installment for those with a bunch of extra time on their hands is the very thorough My First Bike Race webinar video hosted by USA Cycling last year. It covers nearly everything (and a lot more) that a new racer might need to know about getting started racing. It's about 1 hour 20 minutes, with the first 56 minutes being the presentation and the last bit being a question and answer.
