A new watch with built-in GPS from Timex that can tell you exactly how far you’ve traveled and how fast you’ve ran, biked, rowed, or skiied. The Timex Ironman Triathlon Speed+Distance System also works with the Timex Data Recorder (which we’ve mentioned before) with the idea that you can use both to keep track of your performance and try to improve it over time. Similar to Garmin’s Forerunner 201 Personal Training System, which also uses GPS.
