We’re in awe of everything Oscar winners @jimmychin and @chaivasarhelyi do (“Free Solo”!) and today, their latest is revealed! “Edge of the Unknown with Jimmy Chin” premieres today, September 5 @natgeotv and @disneyplus on September 7. An epic 10-part adrenaline-filled series that dives into the minds of the world’s greatest adventure athletes and digs deep to discover what drives the greatest to continue pushing to redefine what is humanly possible, to stare down fear and risk it all? Incredible! #EdgeOfTheUnknown
