I had a great Earth Day run last night. 7.5 miles at an 11:52 pace with 1100' of climbing. That's pretty darn good by my standards. I kicked some butt over the last time I ran this route. It was 5-10 degrees cooler which was one factor, but yesterday was just one of those "on" days.
Here's a pic from last September. I was dead half way through a 7.5 mile run in 95 degree heat.
