Race Course

Race Course Notes

  • The race course is roughly 7 miles in length with the start and finish of the course at the large pavilion.
  • The elevation change is about 500 feet and there are no significant climbs, although there are numerous shorter ones.
  • The race starts heading up the gravel road towards the cricket fields. 
  • There are a few fairly technical rock sections, but they are short and can easily be walked if needed.
  • Lake Fairfax is awesome…come get some!
