About Thunder Valley 

Thunder Valley is located outside of the mile-high city, Denver Colorado. The higher than normal elevation thins the air and makes breaking more difficult. It also has a noticeable affect on the performance of the bikes engine. Riders who have lived in or trained in high altitude are more acclimated and tend to do better at this event.
