Race Details

Course Description

  1. The course is essentially a 12.5-mile lap in Umstead Park that you repeat eight times to reach 100 miles. In that 12.5 mile lap, there are two spurs and then one bigger loop from miles 3.5-10.5, giving runners a chance to see those ahead and behind them for some of the spur miles.
  2. The entire course is very runnable. On the vehicle access road portion of the course leading into Camp Lapihio/Race Headquarters (.4 mile), there is larger crushed gravel that is typical for automotive traffic.
  3. The course is rolling hills with a total of 8,000 feet of climb over the 100 miles (1,000 feet per loop). The entire course is runnable with nicely spaced hills.
