Relentless Forward Progress: A Guide to Running Ultramarathons by Bryon Powell
Relentless Forward Progress: A Guide to Running Ultramarathons

George N, March 2, 2014

Anyone interested in ultrarunning should own this book. Bryon Powell does an outstanding job of sharing an understanding of running, and more importantly, preparing to run an ultramarathon. I am currently working toward my first ultra later this year. My progress falters every time I ignore the information and guidance presented in this book. Thanks to Bryan Powell for helping to get me on track and keep me there. If you already run ultras, this book has much useful information. If you are just getting started, it is indispensable.
