Hello!
Curious how many people have checked of Nick Willis's basic requirements for a sub four runner and have or have not run sub four.
From a tweet of his, if you can run a flying 100m sub 12.5 and run a four mile tempo in 20 minutes, you have the basic bare bones of a sub four miler.
Obviously these seem things that many highly competitive runners can do without even being a sub four miler but am curious how many people are on both sides of the camp with these kinds of metrics.
(Personally i can currently run sub 12.5 in flats with really shitty form but my endurance currently sucks and i can only run a half mile at 5 flat pace)
