A friend completed the 30th Marine Corps Marathon and I am so proud of her!
For myself, running at least four times a week has become the norm but my stamina is strangely inconsistent. I can generally do 5-8 miles now, which is much more than twice my best only a few months ago, and have done 12 miles and even a 21-mile near marathon.
But there are days when I can barely do three or four miles and I can't figure out what the factors are: sleep, nutrition ???
(the picture is the halfway point of my 21-mile run)
