Castlewood Adventure Race

The Castlewood Adventure Race is an off road, multi-sport navigation event held in the St. Louis area. Teams use a map and compass to find checkpoints while traveling on mountain bikes, in canoes, and on foot. The course is unmarked and the exact route is kept secret until race day.

Expected travel on the course includes:

  • 5-10 miles paddling
  • 15-20 miles biking
  • 5-10 miles running or hiking on foot

Organizers advise planning for four to eight hours of continuous movement through woods, rivers, and area roads. Although the event is named after Castlewood State Park, the course may not pass through the park. A course overview is provided closer to the event to help with gear and food planning.

Entry is offered in multiple categories including solo, 2-person, 3-person, 4-person, and a family division with one canoe per team. Published entry prices include examples such as Solo for USD 175, 2-person for USD 350, 3-person for USD 525, and 4-person for USD 700. Previous races had a participant cap of 300 and reached full registration before the end of October. Visit the organization's website for the most recent information.
