Steck says that when he set off from camp he didn't have any intentions of climbing the mountain, but that he was going to climb up to about 7200 meters (23,622 ft) to have a look around and see how he felt. But the conditions were so good and he felt in great shape, that he decided to just keep going up.
Ueli says that he climbed along the British Route, then traversed over the Wieliki Route because of bad rockfall in the night. Eventually though, he ended by exiting on the Spanish Route, although he was more or less just feeling his own way as he went. He did report a lot of snow near the summit, which made things a bit dicy, but still he managed to complete the climb in a very quick fashion.
