Back to back.

It surprises me how much perceived effort can vary.  Thursday's workout called for another series of intervals 6@ 45 seconds with 1 min walking,  following a warmup.

Here's the pertinent details:
Split Time         Avg Pace
1 10:21.9 10:22
3 00:45.6 6:45
5 00:46.6 6:35
7 00:46.0 6:36
9 00:50.9 6:45
11 00:44.6 6:19
13 00:44.2 6:09
15 04:50.1 8:15

Something clicked on interval 3 (split 7) where while I was running fast for me, I also felt light, quick, and in control.   

But what is really interesting to me is how the cooldown lap, split 15 felt.  I was exerting myself, but it felt a lot easier than the warm-up, and I would have guessed I was running in the mid-9s.  All wasn't perfect, though, as I think I mildly strained my right quad.

This morning was a different story.  I could not force myself to run faster.  The good news is for an easy-paced long run, that's okay.  But the bewildering thing is just how much effort it felt like it was taking to run an easy pace.  My lungs were fine, but my legs just wanted to die.

Split Avg Pace
1 10:47
2 10:05
3 10:05
4 10:07
5 10:15
6 10:03
7 10:32
8 10:07
9 9:53

Clunk, clunk, clunk.   What I find interesting is how much harder today's run felt than yesterday's much faster cooldown lap.  The difference?  Today's workout followed an interval day, and yesterday's cooldown lap followed running at close to my maximum pace.  I think it's like the weightlifting phenomenon where a reasonably heavy weight feels much lighter after lifting an even heavier load.

Why were the runs back to back?  Because tomorrow is Skirt in the Dirt!
