Life after snowski

[Sweder]

Sounds like your encounter with winter sports was a good deal more successful than mine, SW. Took a bunch of 11 year-old girls ice-skating on Saturday. Naturally I was expected to join them on the ice and did so, to my credit, despite the certain knowledge that one large skate on my backside would have seen more action than the two strapped to my inflexible feet. So it proved, several of my daughters' pals sympathetically dragging me 'round for a few laps before I staggered off in search of coffee and respite. I sat, numb-bum'd, watching the next generation weave their way through the madding crowd with amazing skill and confidence.

Ah, to be young and fearless once more . . .

I'm certain the altitude experience will serve you well. Skiing counts as cross-training (along with a few slightly less ingenuous activities ).
Stride on, SW. You'll do fine.
