SURVIVAL SKILLS: Knife day! Learn three key survival techniques using just your blade.


Find a 1/2-mile loop nearby. Run one lap at your race pace (fast!); run a 2nd lap at one-minute per mile slower than race pace. Do 4 sets, then jog one lap to cool down.



On one day, hike 15 miles with a 25-30 pound pack, gaining at least 4,000 feet.
On the other day, rest!
