I had to get some hard work in

Quite windy and close to 40 degrees.  

Per my plan, my workout was Sit 'n Kick Reps: 5x (400m @ 64 . . . rest 60-sec . . . 150m @ 21) with a 1200m jog between sets.  My staple caveat: The workout as designed for a 2:00 800m high school runner is 5x (400m @ 64 . . . rest 30-sec . . . 200m @ 28), then jog 1200m between sets. Since I am not able to run 800 meters in 2:00 just yet, I modified the workout accordingly. I had to get some hard work in or else I will lose my momentum.

Even though I had just stepped out of the car from a 6.5-hour road trip, I still went for the workout.  Even though I could feel tenderness in my calf, I went for this workout; I needed it.  

The first 400 was in 64 and required more effort than it should have.  One minute rest.  The 150 came in at 22.

The second 400 felt a little sluggish, thus 65. One minute rest.  The 150 came in at 23.  Argh.

I ran the third 400 in 63.  Feeling good, I also dropped a 21 for the 150.  I was in business.

I planned to run 63 and 21 for repeat #4 as well.  Instead I ran 64 and 22.

Repeat #5: 62 and 22.

I was satisfied with this workout, but I am thinking of slowing up the 400s in favor of a harder 150 or 200.
