That's a great book from the early 70s, a chapter each on the great distance runners: Zatopec, Nurmi, and others. I owned it throughout high school, when I was running track.
As of 1970, the great Emil Zatopec, my favorite runner of all time, had been punished after siding with the reformers of Prague Spring and was off in a coal mine or something--I grew up and thought all my life, based on "The Lonely Breed's" sad dismissal of Zatopec's fate (as of then), that he must have died in obscurity and poverty. It made my day last week to google him while watching the 2012 Olympics and learn he'd had a happy 50+ year marriage to another athlete, had been rediscovered as a Czech national hero after the Cold War, and spent his last decade being publicly lionized for his athletic and moral courage.
So, anyway, yes--Lonely Breed is well worth reading for a runner who's interested in the history of the sport. $50+ is pretty steep, but there must be libraries that still have it, directly or via interlibrary loan. Good luck!
