I'm looking for something that can go from bike, to run and maybe to water and the 310x seems to be an option (as well as Timex Ironman global trainer), but they all seem so bulky - is it a pain for running?


Also, wondering - how useful is the HR monitor to you?

I'm not terribly serious about the sport, I just love doing it (and I ain't bad as there is a gold medal hanging off my bike stand )...my watch died at the beginning of summer and have been going without it. The only way I know my accurate run time&pace is from race results. I'm thinking of getting a bike computer with cadence (don't even have that!) and a new simple ironman watch, or should I go all out and get something like the Garmin 310x, which probably has features I may never use or learn to and benefit from????.... or the Garmin 305 as its not as expensive...
