While I have been chronicling my own Mastering 40 journey, I was excited to talk with Brian White who has been actively pursuing his own. Brian, who turned 40 last spring, has big goals for the marathon, 10k, and un-broken pull-ups. So far he is crushing it but don't let that fool you - he hasn't always been a runner extraordinaire. He was big into lifting for years before starting running in his late 30's. Now, Brian is on the cusp of doing amazing things and It was a pleasure to hear him talk all about it.  You can follow Brian at www.instagram.com/ka2lyst.
