I climbed the CUE stairs from the third floor to the fifth today without really noticing it -- I was thinking about something else, and only realized when i reached the top that I had done the climb without significant discomfort -- a little deeper respiration, but no huffing and puffing and no discomfort in my legs.
Airport Rd. (now called Terre View) in 32:08 - an apparent PB, according to my admittedly sketchy records (though I'm sure I would have recorded a time that was lower!). My time on 3/26 was a whole second slower. While the time was good, and the distress symptoms were not so bad (only spit once), it was really hard emotionally to keep my cadence up as i tired. I managed 26 (156/min) or so on the way out, but dropped to 24 (144min) on the way back. I was just too tired. It's hard to tell just how significant the difference is, but it has seemed to me in the past that a higher cadence brings times down more than any other modification.
