Beginning Mountain Bike Racing in the Tricities TN/VA: Sweat and Gear Without Fear
Natasha Snyder [email protected] Beginning Mountain Bike Racing in the TriCities TN/VA: Sweat and Gear without Fear Natasha Snyder <[email protected]> Author Natasha Snyder and her beloved racing steed on a 35 mile training ride. Alvarado Station Store, Creeper Trail, Abingdon, VA. Natasha is a retired mountain bike racer from Bristol TN who specialized in cross country and cyclocross, with several trophy finishes. Natasha Snyder [email protected] The world of mountain bike racing is exciting, exhausting, varied—and accessible. If you are a competent mountain biking enthusiast who has mastered basic riding skills and built a decent level of fitness, you may be ready to explore the next step: the local racing circuit. With some readily available equipment and determination, you could begin collecting trophies in no time. Most adults who purchase a mountain bikes are simply recreational riders, looking to enjoy a comfortable, ecologically-sound, human-powered ride around their neighborhood or perhaps a quick ride to the beach during vacations. After all, mountain bikes are stylistically diverse, slower and safer than motorcycles, and more comfortable than skinny road bicycles. However, sometimes a casual rider becomes a true “enthusiast,” which is what people involved in bicycle racing call those who are more than recreational riders, but not quite elite athletes. Once the desire to go fast surpasses the desire to arrive home clean and comfortable, the time may have arrived for you to consider preparing to enter a local or amateur mountain bike race here in the Tri Cities and surrounding region. -
