| Route Notes | Team left C3 at 9 pm on 19 May. Weather was good, windy about 50 km/hr. Straightforward climb. They arrived at 5 am and spent about 15 minutes on the summit. They descended to C3, where they arrived at about 11 am. They spent the night there as Wermuth had problems with his eyesight. He had laser treatment ten years ago and during the descent his vision blurred. When he descended to ABC the next day, his vision got increasingly better. They descended to BC on 23 May.
