"Full of euphoric highs. Rusisng with Karnazes [is] like setting up one's easel next to Money or Picasso... His book describes a journey into distance running that is much less about sweat than about the emotional terrain that unfolds at the frontier of endurance."
The New York Times
"[Karnazes'] spirited memoir... can help mere mortals who want to push past their perceived limits or simply jump-start their sedentary lives."
"There is clearly something Nietzschean in Karnaze's makeup...that whatever doesn't kill you makes you stronger.'
Los Angeles Times
"Iron man Dean Karnazes is no mere mortal."
"Makes the extraordinary look easy."
"An exhibition of unadulterated courage and mental and physical stamina [for] anyone who likes to read about ordinary people doing extraordinary things."
"Dean's masochism is a reader's pleasure."
"The perfect escapist fantasy for couch potatoes and weekend warriors alike."
San Francisco Chronicle
"[Dean is] like a comic book superhero who remains undercover by day, every bit the unremarkable family man."
The London Daily Telegraph
"A real life Forrest Gump... [Karnazes] has pushed his body to limits that are beyond masochistic. They're inhuman."
