Purchasing a high tech training tool can be a big commitment To get the most out of your training, though, the choice is quite easy—go with the Polar RC3 GPS.

Designed for everyday use, the RC3 features an integrated GPS system to help guide runners and cyclists through their epic journeys. Aside from tracking specs like route, speed, and distance, the RC3 emulates having a personal coach on your wrist. It gives motivational post-workout feedback, along with a breakdown of how many calories you’ve burned, and how you are progressing as a runner, all to help you hit your goals. Once you're ready to brag about your immense development, the device allows you to share your results with friends. For anyone looking for track heart rate, upgrade to the RC3 GPS HR (of course it’ll cost you a bit more).

Get yours at RoadRunnerSports for $299 ($330 for HR).
