Watch for these - the latest wrist gadgets for runners
Garmin Forerunner 910XT
Set to launch later this year, the latest incarnation from arguably the world's leading GPS watch brand is much sleeker than its predecessors. The all-in-one device not only tracks running and cycling, but also extensive swim metrics including distance, stroke identification, stroke count and pool length.
Nike+ SportWatch GPS
Using GPS by TomTom, the Dutch navigation equipment maker, and the in-shoe Nike+ Sensor, this watch lets you get accurate speed and distance information indoors or out. The USB contacts are built into the watch strap - so it plugs directly into the computer to upload data and recharge.
Finnish brand Polar is the leader in heart rate monitoring watches, and ventured into the GPS arena by creating sensors as optional add-ons. While in the past the sensors were big and clunky, their latest, the G5 GPS sensor, is barely the size of a mobile phone battery. Pair with the watch and you're in data heaven.
Like Polar's watches, this needs an add-on Pod to have GPS capabilities. However, the circular Pod is considerably large, at about 7cm in diameter and weighing 72g.
Timex Ironman Global Trainer
This is a huge watch, but it's all-in-one. It's boasted that it is 'easy to use for those who want a simple speed and distance product, thanks to the thoughtful and intuitive interface that Timex is known for.'
