Hi,
Are you training for military? This sounds like our PRT (Physical Readiness Test) in the Navy. Other tips besides running daily:
1. Fartleks. If you're using a track, run the straights at a faster sprint, curves at a slow pace. Or set up a set distance to run fast followed by a slow paced distance.
2. One day out of the week, run a long, slow distance run (2 to 3miles), don't worry about pace. Your
body's build up of endurance will help you with the shorter run and you'll break the psychological barrier of the 1 1/2mile wall!
3. Start your 1 1/2 mile run at a faster pace for only the first 200 to 300 yards (meters) then resume your regular pace. After a few weeks, you'll find yourself shaving seconds off your run and you won't feel a difference in your exhaustion level after the run.
4. Always strive to catchup to that next person in front of you! Another mental factor that helps you take to focus off yourself. Just look to the next person and say to yourself, "I can catch up to them."
Good Luck,
Cindy
