Well, so much for my speed work.
Was scheduled to run 1.5 x 4 with 800 recoveries, at 10 seconds faster than race pace. I don't know any more what my race pace is going to be, so I decided to just run relaxed and see what happened.
Well, I ran the 1st 1.5 mile at a 6:55 pace, and the second one at a 6:46 pace - so actually not that bad. But then, nothing. I think I felt the way The Flash did when Zoom stole his speed force. Nada - Nothing - Zip.
It was a really odd feeling, because the 1st two splits were not a problem. Same as last week though - I just could not go further. So, I slowed right down and ran the final 4 miles at an 8:38 pace - and I felt like I was pushing to go even that speed.
So, presuming I'm correct in that I'm suffering from overtraining, I've decided to just eliminate all the speed work left before the race (just 3 more sessions) and run everything easy. Maybe that will give me my legs back for the race - which is 3 weeks away.
