Thomas Jefferson 100k

March 14, 2015 • Charlottesville, Virginia


The Thomas Jefferson 100K course is designed along the lines of other well-established multiple-loop courses on the American ultra circuit. Races such as Javelina Jundred in Arizona, Rocky Raccoon in Texas, and Umstead in North Carolina provide runners with excellent opportunities to run long distances over trail without dealing with the complicated logistics of point-to-point courses or single loop courses. While multiple loop courses require a certain amount of mental fortitude they are also wonderful ways for families, friends and spectators to enjoy the race experience along with the runners. The Thomas Jefferson 100K will provide runners with a challenging 100K course in a controlled, manageable environment.
