The Nike+ Sport Watch GPS is a must-have for any runner. If you haven't started working out in January like the majority of your friends, February is the time to start reaching those goals.  You can get instant feedback on your workout - speed, distance, pace, heart rate and calories burned, all while mapping your route and elevation. The Nike+ connection helps find new routes, set personal goals and access training programs on Nikeplus.com. I'm running in the Pittsburgh Marathon in May and I'm going to use this watch to help with the training. What are you training for?
