If you have paid any attention to cool, new fitness gadgets, you know that Polar is one brand that just keeps on popping up. Polar is a leader in heart rate monitoring, known for creating highly-advanced training management systems for athletes of all types. Now, the company has come out with the most advanced and versatile of them all -- the Polar RS800CX.

This device records your route using GPS technology, and it's compatible with Polar's range of W.I.N.D. running, cycling, and GPS sensors so you can track speed as well as distance, no matter what your terrain.

It's also designed with the multi-sport athlete in mind. Many of us don't just go for a run -- we run, bike, swim, rollerblade, and more. The RS800CX allows you to change your data from miles per hour to minutes per mile (pace), so you can always get the appropriate data for your training. Then, you can combine all the data from the different sports into one file, seeing where you're working hard, what you could put more effort into, and then congratulate yourself on how great you are!

The standard RS800CX is perfect for those participating in multiple sports, but if you're a serious one-sport athlete, you're still covered. The RS800CX BIKE is for cyclists, and the RS800CX RUN is for ... well, if you can't figure that one out, I'm pretty sure I can't help you.
