Not doing too good

Suzy is doing very well, using the treadmill 3-4 times a week, but I haven't been on it in... well in a long time. I hiked up tuckerman ravine last week, and while it was painful, I made pretty good time and was still able to ski a solid top to bottom run without much pain. Had it been much harder perhaps I would be motivated to use the treadmill more.
