World-class ultra runner and co-founder of the Vertical Tuesday Running Club, Frank the Tank Gielen steps off the trail and into the studio to chat with Doc. Settle in and buckle up as The Tank covers some serious ground with Doc, including ignoring the suck, just getting warmed up after 80 kilometers, Concrete Clark, Slammers, the Dropkick Murphys, Laz Lake mind farts, hallucinations, dirt naps, the Big Dog Backyard, Belgian math, the Barkley, the family jewels, and how just about everything is doable. Epic guest.
