From what I understood, Killian really didn't even know if he made it to the summit because of the conditions. He also didn't break the record he was shooting for because of illness. His second attempt basically created a record which was hyped up by his sponsors more than Killian. I dont think Killian was happy at all with his "performance" and I wouldn't be surprised if he goes back for another attempt. Killian is one of the most gracious bad a55 skier, mountain runner and competitor in the world.
Check out some of the insane videos he has been posting on youtube!! Also he has been winning 100 milers for 8 or 9 years now as well as countless other races at other distances. His reputation is unquestionable.
