Rob Springer has arrived in Pakistan and is settling in before heading off to Skardu. He is part of the Field Touring Alpine expedition to Broad Peak and K2.
He will fly to Skardu in the next few days. Then set off from there towards K2.
On his blog too he talks about the type of preparation that he has been doing to get into condition for these 2 mountains.
