About Relentless Forward Progress: A Guide to Running Ultramarathons
Relentless Forward ProgressMarathons have become too easy for some runners. What was once the pinnacle of achievement in a runner’s life is now a stepping stone for extraordinary adventures in ultramarathoning. The number of ultrarunners—those running distances of 50k (31 miles), 50 miles, 100k (62 miles), or 100 miles—is growing astronomically each year.

Dean Karnazes’ Ultramarathon Man and Chris McDougall’s Born to Run have inspired tens of thousands to try these seemingly superhuman distances. But to date, there has been no practical guide to ultramarathoning. Now, Bryon Powell has written Relentless Forward Progress, the first how-to manual for aspiring ultrarunners. Powell covers every aspect of training for and racing ultra distances. This encyclopedic volume prepares runners for going farther than they have ever gone before and, in the process, shows them that they are capable of the “impossible.”

Here’s the review of Relentless Forward Progress penned by Matt Fitzgerald (author of Racing Weight and many other books) for Competitor. In short, Fitzgerald wrote, “I can think of nothing that would give me more confidence going into my first ultramarathon than having read this book. Nothing is left out.”
