I am a 55 400, 2:06 800 guy. And around 17-flat for 5K.
If I'm running a 5K at 17:45 pace, should I be able to close the thing in 2:15 over the last 800 and under 60 for the last 400? (trying to extrapolate what the world-beaters are doing)
Is anyone here able to close anywhere near their 400/800 best in races?
