Donski

I heard average time can vary from 3-4 hours depending on fitness. I have a friend, who was hiking up to ski down, do it in in under 2 and a half hours. I think I've read trip reports on TAY where times range from just under two hours to 3 hours without breaks. I'm assuming some of these are during early spring conditions where skinning up might be quicker than bootpacking. As far as jogging up up to Muir, if you are so inclined for an intense workout, the record is around 52-53 minutes supposedly done by a park ranger. I would not be so worried about time my first time up, I'd be happy just to make it for my first time, then I'd worry about time on following trips.
