The Garmin Forerunner 310XT is an excellent running watch. In fact, it is an excellent biking and swimming watch as well! It has incredible battery life (20+ hours) and is a favorite amongst triathletes, ultramarathoners, and runners of all sorts.
I featured this watch earlier this year when it was at $189. Now, it is available (refurb) for $139 at eBay from buydig. They are very reputable and this comes with the USB stick and HRM strap. This is a fantastic deal and if you are looking for a deal, you would be smart to jump on it!

Here is the information from Garmin:

- Tracks time, distance, pace and heart rate on land
- Times your swim and estimates distance and average speed

Finally, a GPS-enabled training device that isn’t afraid of the water. The rugged Forerunner 310XT is the triathlete’s indispensable training tool — a GPS-enabled trainer that is water-resistant to 164 ft (50 m), tracks data in multiple sport modes and sends it wirelessly to your computer. This multisport device has up to 20 hours of battery life, tracks distance, pace and heart rate¹ on land, and goes from wrist to bike in seconds.
