Climbing partners Christian Stangl and Bruno Buchet reached 7600m on the Cesen route in preparation for a joint bid to reach the summit of K2. Buchet reported that the day climbing from camp 3 was tiring. Clearly they did not reach their target of reaching the shoulder of K2. Despite this they might be some of the climbers that Goeschl is waiting to arrive on the shoulder so that there could be a joint asault on the summit of K2.
He said that they spent a difficult night together at this height. The wind blew the tent inwards and it was cold.
