Garmin Forerunner 205

I received this sleek personal trainer as an MBA graduation gift in May of this year. The GPS receiver will track you on your runs and tell you how fast, far, and hard you are training. The included software is easy to use and I've found the mapping features interesting and fun. This is one of those classic devices that I would probably have never purchased for myself, but now that I have it, I truly enjoy it.

From the Garmin Website: Designed for athletes of all levels, this running partner and personal trainer has one goal in mind - to better you. It continuously monitors your speed, distance, pace and calories burned so you can train smarter, more effectively. It tracks your every move with a super-sensitive GPS that even works on tree-covered trails and near tall buildings.
