I run .25 miles in 1.50  on the True Treadmill for the second run, with an improvement of 20 seconds from the first run.  The pace for the .25 miles was 7.23, with Devon Still running a mile in 7.22.  The average speed was 8.1 and the maximum speed was 9.6.  On the first run, the time was 2.10 for the .25 miles.  I warmed up before the run with a speed of 3, 4, 6, and 7 for .05 miles each on the treadmill.  Exercises were completed before and after the run for under 1 minute.  I viewed videos of Devon Still (290 Pound Former NFL Player Runs 7-Minute Mile), Coach Jason at Running Secrets (How to Run a SUB 8 MINUTE Mile | Exact Workouts, Paces, and Strategies), Goal Guys (I trained 8 weeks to run a 5 minute mile...Here's how it went), and Coach Holly (How to Run a Mile Without Stopping).  I walked 3 miles before the run.
