Garmin Forerunner 35
Thanks to its built-in GPS and everyday fitness tracking features, the Garmin Forerunner 35 represents excellent value for money, with both outdoor and indoor running modes, runners will definitely get the most out of it. Additionally, there are also handy cycling and walking modes. And although you can’t use it to track swims, its 5ATM waterproofing means there is no problem leaving it on in the pool. The Forerunner 35 has an optical heart-rate sensor, but if you want the very best accuracy, it can also be used with any ANT+ compatible chest- strap. If you rack up lots of miles on the treadmill, it can also be paired with Garmin’s Footpod for more accurate indoor tracking.
