Fitness Tools For Tracking Calories, Food, Exercise

I had the pleasure (and pain?) of testing out the Nike + Sportwatch GPS for myself at a recent running event in SF. The latest Nike + item to hit the market, this device tracks your run times, distance, calorie burn, and location (thanks to its built-in GPS) and compiles it all up for you to see in visual form on the watch and on your Nike + page online. There's an awesome beta version of something called the "heatmap," which shows you where other Nike + runners are working out right now (more people are represented in reds, while smaller crowds are represented in yellow) so you can join the crowds or try a different route. This is perfect for travel, since you can see where all the popular running spots are in new cities!
