The summit party consisted of five members with two Sherpas: Kausch, McDonald, Pontinen, Toaso and Szabo, with Dawa Jangbu and Philama Tamang. They left C3 for the top at 4:00 am (NST) on 20 May. The summiters were as follows: at 1:35 pm on the 20st, Kausch, McDonald and Dawa Jangbu; at 2:45 pm, Pontinen and Philama. The first party descended to C2 at 4:00 pm, while the second group stopped at C3 at 9:00 pm.

Toaso and Szabo turned back at 8150m, too tired to go all the way to the top, which was not far in vertical terms, but about an hour's trek horizontally across the plateau.

Other non-summiting members:

Cambini reached 7500m on 19 May with the party going to C3; he was too tired to continue and retreated to C2.

Merz went to 6300m on 5 May, but decided to abandon the climb because of a heart condition; he left the team on 10 May.

Mooney quit at 5000m on the way to ABC on 30 April; he was very tired and not acclimatizing, and he he left the team the same day.

Tulit went to C2 on 11 May, but developed a bad chest infection and left from ABC on about the 16th.
