I had a couple of skiing injuries this past winter which curtailed my skiing, though they allowed me to bike at a reduced level. I finally got back on skis yesterday and did a little randonee skiing. I was good climbing on skins, about 3000'/hr. which isn't bad for an old fool, but the descents were tough. By the time I got to the bottom my quads were really burning. Of course it was fresh snow and I took it non-stop, but still.
So what's the best route between here and skiing a stratovolcano in a month? I need to radically improve the strength-endurance in my quads. Lower back is still painful and I have to be careful of it, so that's a little limiting. Hams and glutes are fine.
Biking is going pretty well. 100-150 miles/week with long tandem rides of 60-70 miles now.
