Alain Robert | Legendary Free Solo Climber on Instagram: "Climbing freesolo the Holiday Inn garden Court in Johannesburg back in 1998 has been one of my most difficult building in my entire career and it is certainly one of the hardest building freesoloed in the world with Framatome in la défense and the Sears tower in Chicago. None has been repeated since 1998 and 1999 for the Sears . #climbing #freesolo #challenge #mindset #climbinginspiration"
