Polar Heart rate monitor watch has one. It has GPS, HR monitor etc. look into it. That would be my next watch since the one I have is just a HR monitor, calorie counter etc. by Polar.  Good luck.

I hear from a Polar rep that Polar has a less expensive  GPS model coming out April 1. No, not an April Fools joke..check their web site April 1.

I'm just starting to train for my first 1/2 Marathon, and need to get a watch.  Any ideas for a good basic watch?

Thanks!!
