Running (3-5 miles at a time, 10-11 minutes/mile); also swimming occasionally when I have the time to get to a suitable place and not be rushed. I was on the swim team in high school and still teach lessons sometimes. I also like to hike whenever I have the chance and someone to go with (which doesn't happen nearly often enough--most of my friends aren't interested or if they are we have a hard time coordinating anything, and even the local AMC chapter hasn't had much going on lately other than on the weekends I work!!!). I got snowshoes last winter and wanted to start doing that but we hardly had any snow, so maybe this year.
