The final 2: Marine Corps’ last Harrier pilots complete training

RUN or HIKE? Power hiking if done properly can be very effective, but when do you do it? Using heart rate, gradient or speed as a guide can have too many variables so try using your breathing rate instead When your breathing is getting faster and faster it might be a good time to choose hiking up that hill instead of trying to run it. If you are training for a specific race then the distance. Terrain and time you plan on being out there for can all help your decision when training on the hills!
