It's still really hot, especially in the sun. In the shade it's not too bad (85 degrees at 8:00), but in the sun it is painful and feels much hotter.
Anyway, the good news is I took my knee out for a walk today and all went well. There was no pain, even after yesterday's 60 mile bike ride. I had hoped to do 8-10 miles but I was walking on the track with no shade and I ran out of water. I decided there was no reason to push it today and stopped after a little over six miles.
I'm just glad I can finally get back to training. Sitting around idle has been agony, but now I can focus on my goals again.
Thanks to everyone for the supportive comments during my convalescence!
