After not skiing for ~15 years, it looks like I'm getting bitten by the bug again.
Now, I ski all morning, eat a light lunch (soup and a clif bar) and digest my food. Now, however, I notice that I am a lot stiffer in the afternoon, and more easily fatigued, which reduces my ability to engage the snow with the zeal that I did in the morning.
Couple that with the condition of the runs in the afternoon, the higher prevalence of kids (the ones who go down the hill backwards) who tend to lay around in groups in the middle of runs (what's up with that?), and I've been heading home by about 2:30.
On the one hand, I think maybe it's because I'm older or I'm not used to skiing a full day yet, but then on the other hand maybe I'm just giving it so much in the morning, going for the rush, that it's "normal" to can it before the lifts close.
What's your take on this, and when do you call it a day?
