I have the 830, as well as using Garmin Connect as a source of tracking my progress (connect.garmn.com) You can track just about everything you would like by adding reports to the dash board. You can setup and track goals, create routes to send to your 830 etc. Its pretty comprehensive. By clicking on an individual ride, you can look at all the metrics IE heart rate, speed, cadence, Training effect etc. I also have Strava premium, which does more or less the same stuff, but will give you a graph of where you should be in terms of effort to keep growing. Its nice to have, but not necessary.
