Runners World
It has features unique to Polar including Own Zone which uses heart rate variability during your warm-up to set a heart-rate target zone for that session and a fitness test which predicts your VO2 max. It also lets you record detailed heart rate information for each rep you run, or every split in a race providing you with your maximum and average heart rate for each lap. You can then load all of this information onto Polar's Personal Trainer website. I sounds complicated but the RS200 is easy to use.
In conclusion...
The RS200 is designed specifically for running and as a result has stacks of features useful to both beginners and serious athletes alike.
