This watch gives me all the data I need. Pace per k, k’s per hour, time, distance, heart rate ( only negative on the watch is it’s a little erratic – had mine up to 250!) lap times (adjustable) down loadable. It compliments my plans and my running, I’d be lost without it.
It’s a little on the large size, but that also gives you 4 different screens that are easily readable (well to me at least!) It’s light weight and has a backlight for night/early morning running. It also sync’s with your mac or PC wirelessly as soon as your within about 5 meters.
