25th May 18:39: All the members at the top camp except Nick have left for their summit bid. Nick was still recovering from the journey up to 8300m. He will leave at first light (about 4.30am) and ascend to the ridge but no longer has intentions of reaching the summit. Zac and the group bringing up the rear are about a third of the way up the exit gullies heading to the Northeast Ridge. At this stage it's believed none of the team have reached the ridge yet but the weather is good and virtually no wind for now.
