After telling Barry that I ran my first mile in 5.38, went through 2 miles in 11.26 -3 miles 17.38 - 4 miles 23.43 - 5 miles 29.47 and finish with 37.02,
What went wrong with your pace control button as you were WAY TOO FAST in first mile .You were on for 34.48 10k after a mile and that is too fast .
For every second or minute you are too fast in the first part you will lose double or more of that in the second --and thats how it proved .
You should be looking for Equal or Negative splits . In my last 10k race I ran 1 min faster for the second 5k than the first --to win National M65 10,000 a few years ago .
In winning World Games in Helsinki splits were 14.40 and 14.10 so 30 sec difference there . Get the idea! Any mug can fly out at the start but it is the last mile that counts .
You blew it !
I told Barry, well I'm not sure I've ever run a negative split, even in my 10k p.b. [ 34.52] I ran 5.11 in the first mile,
in my fastest 10 mile [57.36] I ran a 5.14 first mile and even my marathon p.b. had a couple of 5.59-6.00 min miles early on.
It seems I still have a lot to learn
