Announced earlier this year, the TomTom Runner and TomTom Multi-Sport GPS watches will be priced at £149.99 and £179.99 respectively.
Following the launch of its collaborative sports watch effort with Nike for the Nike SportWatch, the satnav makers are going it alone this time for its sporty timepiece that tracks performance data for enthusiastic runners, cyclists and swimmers.
Both ultra slim watches are equipped with sensors to track indoor training and feature QuickGPSFix technology taken from TomTom's satnav range to boost GPS signal pick-up outdoors.
There’s also Bluetooth Smart support letting you hook up a heart rate monitor and other Bluetooth accessories.
Data can be uploaded to the TomTom MySports website and running websites including RunKeeper and TrainingPeaks. You can expect around 10 hours of battery life in GPS mode and both include standard watch features including an alarm to get you up for an early run or bike ride.
The more expensive Multi-Sport watch includes all of the Runner’s features but also adds a dedicated bike mount, cadence sensor, a built-in Altimeter to track elevation and a swimming motion sensor.
