Thanks for the comments.
Just got back in, been a good day, learning how not to fall over on skis. (mostly)
Certainly skiing is an energetic sport, it was reckoned we used about 1500 calories this morning alone.
I have aches in my legs, knees, hips, and some areas I didn't know I has muscles in.
And a bruise on my backside that is going to huge when it comes out fully.
So, on the way to recreational standard, just a bit of work to exercise the knees and hips to make sure I can get the snowplough sorted, and stop a bit better.
Even better news, after a couple of hours on the slope, dinner was leek and potato soup, quite sweet, with a bread roll, and I went for the healthiest option, tuna sandwich, quite a hefty white seeded bread, tuna salad filling, small side salad, and tortilla chips. I left half the bread crusts.
Tested about 1 and 1/2 hours, to an hour later.
5.7, well chuffed.
(especially after the 5.6 start to the day)
Then back out for another hour and a half of exercise.
Now with my feet up, and I maybe be setting into a sitting position!
