I posted late in the old sub 20 5k thread. I made my first attempt at the distance on 6/23. It didn't go well. I was 6:33 through 1 mile, 13:14 through 2 miles, and wound up with an almost shamefull blow up - 21:12.
I could tell 1 mile in that there was no way it was gonna happen. Still, I was close to a friend who I thought I had a shot at through 2 miles. When he left me during the 3rd mile I lost focus and slowed significantly.
Oh well, next shot will be 7/22. I hope to break 20:30 that day. I may take another shot at it late fall.
Good luck all
