GPS Tracking Watches

Do I need a GPS tracking watch?

GPS tracking watches can help you to track your distance and your speed when you are training to run a marathon, doing a triathlon or even just for a casual hike.

The advantages of having a GPS tracking function on a watch allows you to track your performance and feedback to you whether your training is effective or not.

So now, as you might have found out that I am trying to train for my IPPT, and I am trying to get Gold award for the cash reward (to give to my wife), I have been thinking of getting a digital watch that does heart rate, countdown timer. With just these 2 functions, I can train better for my IPPT 2.4km run, and I can get a Timex for about $60. But I also have intentions of running a mini triathlon and maybe half marathon in the future, so I was thinking, do I need GPS function on my watch?

What do you think?
