OK so i am looking at getting a new HRM/Computer before i begin my IM training latter this fall. I am looking at getting one of the many garmin products. I am interested in the 310, but i am wondering if a dedicated bike computer like one of the edge products and a simple watch/HRM for running would be a better solution. So i guess really my question is what do you use and if you could change what would you go with. Thanks for your opinion.
