Legs still tired this morning from a tough metric in hot, humid weather last Saturday. I expected as much yesterday but thought my legs would feel fresher today. Not, but it could also be the weather -- hot and humid again. We have had just as many 90+ days this year so far as in 2010, which shattered the all-time record for 90+ days here. I was hoping last summer was a once-in-a-decade occurrence, but I'm afraid it might be the new norm with climate change.
