With age (I'm right there with you) comes some wisdom. I can't imagine doing that in one day. The acclimatization alone would be too much for me, even going a day early and hiking to maybe 11,000 the day before. And with snow and having to do the Chute. I'm going in from Kearsarge in three weeks and will take an easy four days to do the whole thing. And hopefully, most of the snow will be gone.
