I am not sure I would have been able to power through that.
The issue was that there was not option to stop. So I had to keep going. I couldn't helicopter out of there or anything - not that I would have, but...
My friend did better than I did which was surprising because he had injured himself quite bad a couple months prior. I can't remember if it was a torn ligament or what but it was fairly bad. He didn't seem too concerned about it during the hike though and didn't complain.
The scenery was very nice all around.
