In the morning the guide estimated the return trip would take 4-6 hours. We came back to Bujuku 12 hours later. I was well acclimatized and felt strong in the beginning but the weather was not favorable. There was scrambling, rappelling, mud, a bit of a bog, more than light winds, glacier and above all bad visibility all the way. Some parts took longer than I had hoped for mainly due problems with crampons and ropes and I think waiting in the cold made me more susceptible to catch the cold that I had the following day.
