TODAY, RUN 3-5 1-MILE REPEATS (12 miles total): Today we're introducing a new training technique, "mile repeats". These are a series of 1-mile runs to help make your legs and feet work more efficiently. Try to run each mile in about 8 minutes, 5 seconds, which is 30 seconds faster than you want to run in the race itself. If the day is warm, you have to slow down: 18 seconds faster per mile if the temperature is 65 degrees, 15 seconds faster if it's 70 degrees, 12 seconds per mile if it's 75 degrees, 9 seconds per mile if it's 80 degrees, and 5 seconds faster if it's 82 degrees. Above 85 degrees, don't do the mile repeat session; wait for a cooler time. Walk 400 to 600 meters after each mile, or more if you need to.
