Grand slamming with Andre Blumberg

Come listen to Andre Blumberg, Hong Kong's first ultrarunning ‘grand slammer’ and founder of the Hong Kong 4 Trails Ultra Challenge. One of the few people in the world to complete America’s four oldest 100 mile trails within a 10 week period, Blumberg is taking a rare breather and making time to chat about his transformation from party animal to ultrarunner.
