Relentless Forward Progress: A Guide to Running Ultramarathons Review: Worth having! - Well written, full of factual information, practical. For a seasoned marathoner like me it's a practical guide how to approach my first Ultra. Review: Very informative, albeit slightly vanilla - Let me get this out before I say anything else: those solely looking for a page turner need not apply. This book does not function as a story; as it says in the title, its a guide. I bought this book just because I had read just about everything else about running, so I figured why not. Although I am slowly making a foray into ultramarathons, I was not thinking of using the book as it was intended for, merely, something to hold me over until I found the next great read. I took me a month to finish the book. Powell definitely does not embellish his writing here, just right to the point. Now my next point: This book exceeds its job as a guide to ultramarathons. It contains an exhaustive list of subjects to prepare the reader for their big race, ranging from the 50k to the 100 miler and beyond. I found myself nodding my head with inquisitive satisfaction quite often. I would highly recommend this book to anyone looking at their first ultra, or even to those veterans looking to add some refinement to their training. ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #307,206 in Books ( See Top 100 in Books ) #70 in Extreme Sports (Books) #262 in Running & Jogging (Books) | | Customer Reviews | 4.5 4.5 out of 5 stars (975) | | Dimensions | 6 x 0.5 x 9 inches | | Edition | 3/30/11 | | ISBN-10 | 1891369903 | | ISBN-13 | 978-1891369902 | | Item Weight | 2.31 pounds | | Language | English | | Print length | 232 pages | | Publication date | April 29, 2011 | | Publisher | Breakaway Books | ## Images ![Relentless Forward Progress: A Guide to Running Ultramarathons - Image 1](https://m.media-amazon.com/images/I/81Dk90dSSwL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worth having! *by B***K on August 29, 2025* Well written, full of factual information, practical.

Some sections have guest writers who are established ultra runners. If you love reading about running and/or are intrigued by ultras, then you are going to devour this book. Before buying “Relentless” I checked out some of the reviews. Most were overwhelmingly positive, but there were a few negative ones, and the recurring theme seemed to be that readers found the book a bit basic. I admit there was nothing earth-shattering here. Critics mentioned that the book isn’t so different from marathon training guides. This is also true. A lot of the topics, on things ranging from training runs to hydration to foot care, were similar to what you’d find in a marathon guide. The very simple fact is that an ultra isn’t radically different from a marathon in terms of training. You should probably still do speed work, tempo runs, easy runs, and long runs. I think there are a couple important points to consider with “Relentless Forward Progress”: first, you can’t please all of the people all of the time, meaning that there are going to be a range of audiences for this book, all of whom have different expectations. There are those people who’ve never run anything longer than a marathon and are considering the ultra distances. There are those (like me) who’ve experimented with 50Ks and 50 milers and are toying with the idea of 100 milers. Then there are the 100 mile vets who continue to read every how-to guide they come across in hopes of gleaning new insights. This last group may be somewhat disappointed by the surface-level topics Bryon Powell covers. He’s trying to reach as many people as possible, so by necessity he can’t be overly detailed. You’re going to get a taste of the things you’ll likely encounter when you start running ultras; that’s Powell’s goal, and he achieves it here. And in Powell’s defense, I don’t think any ultra training guide is going to satisfy certain runners because what they’re searching for is the panacea to ultras. The secret is that there is no secret. Every potential problem that crops up in a marathon, from blisters to chafing to hydration issues, gets multiplied many times over in an ultra. Throw in nutrition, trail running, night running, and sleep issues, and you’ve created a huge challenge for any athlete. And there’s no one book that will help you overcome these challenges. You have to just run the distances and learn from experience. Powell says as much. He basically writes that he can help speed up the learning curve but there’s no substitute for experience, no magic pill that will prevent the lowest lows of mile 70. Take Powell’s advice and put it into practice. Ultras themselves are as idiosyncratic as the people who run them. One person may be struggling at the same time another is doing great, and that same person might crush one 100 miler and DNF the next. The real secret to the 100 mile seems to be the mental angle—how to stay positive and keep moving forward—and I think that part is individual to each person. You’ve got to figure that out for yourself. But if you want some great hints on how to dress for rainy weather, how to prevent blisters, how much to run in training, etc., then read this valuable book. ## Frequently Bought Together - Relentless Forward Progress: A Guide to Running Ultramarathons - Training Essentials for Ultrarunning- Second Edition - Hal Koerner's Field Guide to Ultrarunning: Training for an Ultramarathon, from 50K to 100 Miles and Beyond --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/3654883-relentless-forward-progress-a-guide-to-running-ultramarathons](https://www.desertcart.hr/products/3654883-relentless-forward-progress-a-guide-to-running-ultramarathons) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-04-25*
