I was able to go for a run along one of my favorite trails before our softball game last evening. It was a bit more taxing than I had planned despite my mild pace. I couldn't quite figure out what was different until I finished with my run and reviewed my trip on my Nike + Running App. It has a temperature feature which recorded the temp at 90 degrees! No wonder!! :) It was great to be out there and I didn't' feel any pain in my knees! Yey!
