I'm not a big history or military buff. However, I always associate June 6th with the D-day invasion in Normandy, France during World War II. It was one of the largest military offenses and it turned the tide for the Allied forces during World War II.
I didn't even know national running day existed until last year. Yesterday (June 6th) was a planned rest day for me. Over the weekend I did some stroller running with my son, on Monday I lifted heavy and I destroyed my legs doing squats and lunges. On Tuesday I ran 7.3 miles on the treadmill in an hour. I've been feeling weird about running lately. I was almost worried that I wouldn't be able to finish the hour before I even got started. My legs were tired from Monday's workout but, I had some great tunes to rock out with and it felt good.
