For his thirteenth marathon in thirteen days, Dean Karnazes ran the 26.2 miles in 4 hours and 16 minutes. It was a little slower than usual--but, not because of a slowing pace. It seems that a restaurant along the way attracted his attentions--it was called "Lucky 13"--and he just had to stop for a photo-op. And so goes his Endurance 50 quest. Next stop: Bellview, Washington.
