I Bought "Relentless Forward Progress" Then Set a 50K PR

It's true!  I bought Relentless Forward Progress by Bryon Powell on Thursday, April 21st, then 2 days later ran a 4:19 at the Double Chubb 50k trail run in St. Louis.

Are these 2 things directly related?  No, but it did happen and if you are planning to run an ultramarathon or bumping up from 50k to 50 mile or 50 mile to 100 and beyond, you would wise to pick this book up and read it.  Also, make sure to check out Relentless Forward Progress Launch Week over at iRunfar.com for some chances to win some sweet gear today - Friday from some of the biggest names in trail and ultrarunning.
