Way better than Tuesday run

The IGP™ called for 40 min 5r 1.5w today, and Tuesday was 40 min 5r 2 w. Today the very same 5K was done in 37:45, compared to Tuesday's 41:32. There was no particular push to run fast. My legs felt much better and the run felt smoother. My hams weren't complaining at all, and I could feel all of my calves working, but no pulls or tugs or complaints there either. I'm pretty sure I could have done a couple more walk run cycles at this pace, but this is a lighter week for me, and I know I need the easier workout. From my experiences in other workouts, I get the feeling that this was one of the days it came together, and I could see a big improvement without feeling like I was working really hard. Much more efficient. But on this sort of thing I've found if I push harder, thinking I'll get even more improvement, it all tends to fall apart. So I just enjoyed the run today on a beautiful morning, about zero C, no wind. This can't last.
