Relentless: Seven Marathons, Seven Continents, Seven Days

Dr. Geithing is a great memoirist! It has been a while since I could not put a book down. A real page turner as other reviews mentioned. Love the way he brings in different concepts including alpha male and I learned a lot about sports and esp. cycling. I had a few belly laughs too, very inspiring for anyone who does any amount of exercise/sport

Really interesting read. I devoured this book in a few sittings. David shares his inner most thoughts and allows you to live each marathon with him. You get to feel all the pain, frustration and joy with each marathon.A terrific read for athletes or anyone interested in what drives and motivates us.Loved it!

Some parts felt a little repetitive. It would have been nice to read more about training and planning for this amazing challenge.

Great read - easily the best and most entertaining non fiction I've read this year and probably decade. Written in such a captivating way you race to the end with David. What an achievement as well, cannot imagine the toll such a race would have on your body. Highly recommended for anyone looking for inspiration to take on what seems like insurmountable odds.

For athletes and non athletes, a gripping read. David G provides a wonderful and honest (often painfully honest) account of an extraordinary feat. His achievement, as a full time professional vet, is remarkable. As a runner I was captivated and inspired to do more.
