I have been looking into an Edge 305 GPS bike computer to replace my old and outdated cateye/polar combination. I have had only bad experiences with polar - unfortunately. The interference from every powerline, phone line, other cyclist and so on makes it unreliable.

As I also would like to use the Edge 305 during run training, I wonder if anyone has a comment on the functionality for running and is it worth it? It seems a great bike computer but I am not sure it works when used for running and it is larger than the others.

thanks,
