You are lucky you are not paying double! I've recently found out that a lot of the people I go to my classes with belong to one or more gyms and/or take classes on a pay as you go basis elsewhere. Of course, they are not spending what i do on cycling and x country ski related gear, even if they have a bike!
My friend emailed me with our ski totals from Saturday...14 km. Probably one of my longest skis and I should not have done as much, although it did not seem like it was that far.
I am hoping what I am feeling is just weird muscle soreness, as I have been known to have strange muscular reactions to heavy exercise. It's never happened from skiing, though, but I definitely did too much. Glad we didn't ski today. Our friends ended up staying and doing about an hour and a half, but I was all unpacked and done with my grocery shopping (we're in that "we're gonna die in a snowstorm" panic around here right now) before they got home.
