This is a very demanding mountaineering course that requires participants to be in excellent physical condition. Invest the time to train well beforehand and you will not only enjoy the course more, but you will also gain the satisfaction of being a solid member of the team as you climb. Be prepared to carry a 50-60 lb pack and pull a 20-30 lb sled for up to five miles at a stretch. Be prepared for temperatures well below freezing at night, with daytime temperatures very comfortable and sometimes hot!
