At first I thought this thread was about how to recover from a hangover.
I went on a fairly ambitious 2 week ski trip earlier this month with my adult son. Skied 11 of 13 days. Had one prior ski day this winter before the trip. I'm a moderately fit, pencil pushing office dweller by trade and live at sea level. Logged nearly 2000 miles on rental car during the trip visiting multiple ski areas. I turn 60 in 2013. Must admit it was a fairly grueling ski safari schedule and has left me with a bothersome left knee.
I have no special recovery regimen to share, I just try to apply a little common sense: moderate alcohol, try to allot 8 hours for sleep, no special food, drinks or supplements, but I carry water on the slopes at higher elevations, got only about two hot tub sessions during trip, but agree those are relaxing, took some long hot showers as an alternative, stretch in the morning, eat some fruit for regularity.
This was not my first ski safari and I eat light on these kind of trips and generally drop 5 or 10 lbs by the end. It's sort of a ski-monk type of existence, sounds boring, but I like it all about skiing. Brown bag most lunches, cook simple meals at night, rarely eat out. One of these days I have to do a trip where I stay at the same ski area all week.
