NEW! We are excited to announce that PATHFINDER has partnered with Green Beret Fitness to create a training program for their premier OPERATION STIRLING event in Brevard, North Carolina. (Read more about the event here.) Even if you've got one of their smaller events on your calendar or are looking to train to peak performance, this is an incredible training plan for our toughest rosters.

This training plan focuses most on long, heavy rucks, hilly and mountainous terrain training, and increasing your endurance base to handle multiple days of rucking in a row. This is for athletes looking for an incredible challenge!

Green Beret Fitness is offering a 10% Event discount for all PATHFINDER Stirling program finishers. This is an excellent motivation for training!

PATHFINDER isn't a day-by-day workout plan ... because they don't work! PATHFINDER works because YOU build it. We give you the requirements - miles, workouts, and Challenges - and you fit them into your calendar based on what works for YOU.
