Stirling Back to Back Day Challenges - Everything You Need to Know

Stirling Back to Back Day Challenges

This Challenge must be executed over the course of three days - back to back. This Challenge will not count for completion credit if it is not completed in this manner. Up to (3) three attempts may be made for completion. There are no exceptions to this facet of the requirement.

Challenge Purpose

  • Physical conditioning over a three day course mimics conditions of the five-day Green Beret Fitness OPERATION STIRLING Event and is excellent preparation for gear, feet, and fitness.
  • Mental conditioning for the PATHFINDER athlete to sustain extended evolutions during endurance events over a multi-day period.

Challenge Notes

  • Ideally, terrain for each day of the Challenge should be done on hilly trails and with noticeable elevation. The terrain in the Appalachian Mountains of the Pisgah National Forest, where the OPERATION STIRLING Event takes place, has elevations up to 6,000 feet and contains some of the highest mountain ranges in the eastern United States.
  • There are NO TIME PARAMETERS for each day of this Challenge. However long it takes is how long it takes.
