Mystery of Time

Today I do speedwork using the mile loop around my house. I’m supposed to run 1600 m at 6:41, 3200 at 13:42, and 2 800s at 3:13. There are rest intervals varying from 400- 800 meters. I am nowhere near hitting the paces on any of these runs. I can barely get below a 7 minute pace, and for the 2 mile interval, I’m running at a 7;15 pace, which is what I was supposed to run for 1 3 mile tempo run last week. I have done these workouts in 2 previous marathon training seasons, and while I may have not nailed each one of them, I had way better overall results. If I am slower for speedwork, I can accept that. I want to know why I am slower – is it because I am older, heavier, my plantar fascistis, bone spur on my left foot. Could it be because I am not doing the type of plyomtric drills I did before I ran green bay last winter? What is odd is that my indoor track workouts are way faster, for supposedly some of the same distances. It makes me wonder whether we have the distance wrong for that track, and its really not 200 meters. I am going to start asking around.
