Wear a Helmet!
On Friday I witnessed a hard crash at over 20mph in which a rider in my group broke an orbital bone and suffered a concussion. Fortunately, he was wearing a top-of-the-line helmet or it may have been much worse. The rules of UCI (the governing body of professional cycling) require all riders to wear a helmet at all times. Just wearing a helmet isn't enough. The helmet much be properly fitted and buckled to your head. The Brain Injury Alliance of Kentucky offers some good resources about brain injury prevention. One of those resources is a short animated video designed to teach students about the need for wearing a helmet and how to wear helmets when biking or skateboarding. In the video students learn how to pick a helmet and how to properly fit a helmet.
