Alex Honnold made it savely to the top of Taipei 101 tower in 1:31h.The difficulty grading is estimated to be around 5.11c (6c/6c+), which is a medium technical difficulty for experienced climbers, but still hard when you do it for 1,5h on a very exposed building.via @gripped https://gripped.com/profiles/alex-honnold-free-solos-taipei-101/Edit: fixed french grading to 6c.#climbing
