I set out to do a 14 mile run with 15 second bursts every 5 minutes. I started out great and then began tapering off bit by bit arouns 9 miles. It came to the point that I was walking the hills that I was running in my 10 mile run two days ago. It really sucked.
It got to the point that my 15 sec intervals were occurring on the hills and it was completely ruining my workout. I decided at 12.6 miles to stop ans get more water because it was taking longer than I expected.
However, when I stopped, I decided the rest was all junk and I should try again Sunday….
