I've got two real good reads for you.
An elite first time Boston Marathoner tells His story from the front, like way up there. Check out the part of the Kenyans horsing around.
The next is from a fellow blogger that I follow who just broke another marathon PR! Wayne ran the Hamburg Marathon in a time that I hoped to have been running by now.
Its interesting to read and learn from these accounts as there may be something for the rest of us to apply in our own marathoning, consider this as part of your acquired learning experience.
easy 80 minutes yesterday in unusually dry oppressive 95 degree heat out in the Reservation
today a "quick" 5 miles in ~34 minutes on Haynes Loop as cooler temps prevailed
