Funny that @adamengst should post this in the weekly recap yesterday:
Today I went to the Newfield track to do exactly this and see how long it would take to run a total of 1 mile at sub 4 pace. I planned on running 100 meters at a time every 2-4 minutes.
I lined up at the mile start and covered the first 109 meters in 17.8 seconds. On subsequent reps I used a running start. I ran the next 11 100s between 14.0 and 14.8.
In lap 3 my legs started to feel like they were filling up with sand, but the individual reps were short enough that I wasn’t struggling. I decided to run the last lap as 2 200s. I managed to squeeze out a 28.2 and 28.3 by running all-out. The total running time was 3:53.3, but the Challenge-legal time including breaks was 34:43.
This was probably an inadvisable workout. 1 mile is a lot of ground to cover at a pace that is significantly faster than my 800 meter race pace. But it was a fun bucket list workout to run a sub 4 minute (really a sub 40 minute) mile.
