A running site that I go on frequently everyone recommends Garmin Forerunner the 301 has hr monitor, pace calculator, GPS, you can download your runs into the computer, and compare. Set a pace you want to run with and it'll let you know if you're on pace or not... all kinds of cool stuff lol. Set a predetermined W/O and it'll go through it with you. I personally am not too interested in the HR monitor and so I want the 201 or 205
