What A Difference

Amazing how much impact the temperature and humidity have on running performance. Last Monday, in the middle of a brutal heat wave here in New York, I struggled (a lot) to run 4.5 miles at a 10 minute per mile pace; at the time I ran it was about 73 degrees with high humidity.

Today is beautiful - it's a bit below 60 degrees with moderate humidity. Just back from a 7.1 mile run which I was able to do pretty comfortably at 8:18 per mile. I was just shy of a PR for this route - missing by about 10 seconds.

I'm running in the Chase Corporate Challenge later today - 3.5 miles in Central Park. Planning to take it easy.....
