Simply great. One of the world’s best ultra runners wrote about his quest to set a new FKT (= “fastest known time”) for covering the 2,200 miles (3,500 kilometers) of the Appalachian Trail. Spoiler: he did it. But the journey was immensely tough and you live it all through with him while reading this. I’ve read a bunch of reports about crazy races from athletes, but rarely one is so eloquently written, captivating, and full of variety.
