Could never do it due to condition limiting oxygen to my right leg below the knee, so I'd be toast above 16k feet I'm guessing. Also, I would imagine it would be difficult to afford the time to train for the climb, even if I could qualify medically. Perhaps I'll be able to make an attempt in my next life!
You need to establish a resume of climbs..You need high altitude experience.
After I was on Rainer I looked into Aconcagua..High altitude but not very technical..
Getting in shape is easy, finding the time and cash is the problem.
For that same 60K you could take 5 friends on the heli ski trip of a lifetime, especially this year with the low Canuckistanian dollar. It would be way more fun than slogging up Everest with a bunch of other affluent sheep.
