Could this be a promising sign?

July 31, 2018

On tap today was 6 x 2:00 at 5K goal pace with a 2-min jog recovery between efforts. My goal is sub 18:00, about 5:47 or less/mile.  At this pace, I should have covered about 550-560 meters per repeat. (42 seconds per 200 meters)

#1: 560 meters

#2: 565 meters  

#3: 560 

#4: 570

#5: 570  

#6: 580 

#7: 590 

#8: 600 meters 

I averaged about 10 additional meters per 2:00 repeat over last week's effort. And I didn't feel as winded as I did last week. Could this be a promising sign? 

Tomorrow is another 45-minute run.
