This is how fast they are running per 100m in a 5K.
12:37 = 00.1514 a meter = 15.4
13:00 = 00.156 a meter = 15.6
14:00 = 00.168 a meter = 16.8
15:00 = 00.18 a meter = 18
16:00 = 00.192 a meter = 19.2
17:00 = 00.204 a meter = 20.4
How the **** can people run 18 second 100 meters for 5000 meters? Do you have to be able to run sub 12 100 meters to not be in sprinting form when running this fast?
I can run a 13 second 100 meter but I can't imagine running that speed for 5000 meters, it's insane. My 5K best is 19:50. I run 25 miles per week. I'm not messing about with this LSD crap anymore, I'm running at 18 second 100 meter speeds, until I run out of breath and try again for my daily miles. Teach the body a lesson.
