Garmin but what Garmin?

The only difference between 205 and 305 is that the 305 has the heart rate function and the 205 doesn't. (Same with the older series 201/301, which is what I have.)

The wrist-mounted series are called Forerunners. The Edge series are intended more for cycling, but they do have the same multi-sport capability as the Forerunners. I know other people who also carry theirs while running, but personally I need the wrist strap. The tradeoff is the smaller display.

The latest Edge models (605/705) come with street mapping functions as well, just like the GPS units they sell for motorized applications. But they're even bigger and bulkier than the Edge 205/305 and I think they would be very hard to run with.

I don't know too much about the Edge firmware. With the Forerunners, the unit itself only accommodates one user profile at a time. Garmin Training Center is the software that resides on your computer to download your data and upload user profiles, routes, and workouts for all their GPS units. Garmin Training Center for Windows allows multiple user profiles, but the Help file says that you still need two separate devices, each with its own profile.

The latest wrist-mounted Garmins are the Forerunner 50 (no GPS) and 405 (similar to the 305, but more watch-like, with a smaller screen, and with wireless connectivity). I don't know a thing about those other than what the website says.
