A lot of skiers like to bike to stay fit in the off-season. Not me. I’m a runner. Maybe I just hate my knees, but I always train for and run a few races a year. The Forerunner 405 has a built-in GPS system and can track distance, pace, calories burned, and heart rate, among other things. And it can also keep track of your vertical—handy once the ski season rolls around. —Scott Gornall, Associate Editor, Skiing Magazine
