I was a high school runner in the mid 2000s, and my coach had a first addition copy he lent out. I might have been the only person on the planet who did not like it.
I found the writing style to be overly fluffy, and as a female runner, I couldn't relate to the time period where women weren't included as athletes. Some of the descriptions were relevant (particularly the last 100 of the mile being something you can't truly ever imagine in your head), but others were not.
One thing that's outdated about OAR is the notion that you have to absolutely kill yourself all the time and sacrifice everything in order to be great. We know now about rest, recovery, balance, and healthy eating (no, I was not downing big macs every day in training) and how important that is to being the best. No, you actually don't have to give up the love of your life in pursuit fo greatness either, actually the love of your life in your life will probably help you.
Perhaps it was the time period change but I related to Running with the Buffaloes a lot more. Same relentless "character" and the team dynamics were very relatable.
