That was Goran Kropp, the Swedish soloist. I believe he biked from Stockholm actually. And he hauled all of his gear all the way. He didn't hit Cabela's at the Makalu exit and load up. Unreal. I'd like to get a hold of his book. I heard people were throwing rocks at him along the way (in some unsavory parts). Nonetheless, on his first attempt, he turned back 300 feet from the summit because he believed he wouldn't have the strength to get down alive. He supposedly received support from the IMAX crew in the form of a half stick of butter before he summitted.
Sadly, he died on a roped climb in Washington 2 years ago. I don't think I'd classify him as a "sissy" either.
