National Ultra Endurance Series


The National Ultra Endurance Series is an ultra-endurance mountain bike race series in the United States. It was established in 2006 in order to bring national visibility to ultra-endurance mountain bike racing.
The number of races has varied from year to year. Each of the races is approximately 100 miles long and primarily off-road. The title of series champion is awarded to the racer with the four best results in each of the following categories: Men's Open, Women's Open, Men's Masters, and Single speed. Any ties are broken by the placing results in the final race of the series.
