I'm currently running using the Nike+GPS app on my iPhone 4.
However, I would like to integrate a Polar - or any other brand - heart rate monitor into my sessions to boost my performance.
Can anyone recommend me a heart rate monitor device that integrates with Nike+GPS and my iPhone? (if that even exists)
Thanks in advance!
