6 running watches to help you train smarter

1/ Garmin Fenix 5S

Compact do-it-all watch

The multisport Fenix comes in three sizes, of which the 5S is the smallest. Suitable for thinner wrists, it has a 14-hour battery, barometric altimeter, magnetic compass and heart-rate sensor. All three Fenix models keep tabs on your stride, measuring cadence, ground-contact time and bounce, as well as estimating your VO2 max.

Get it for £500 from Runners Need.

2/ Polar M200

Smart-money choice

While the price tag on some GPS watches could have your heart-rate monitor registering a few skipped beats, many connected features have trickled down to more affordable models. The M200 is an all-day activity tracker with a built-in heart-rate sensor, accurate GPS and basic phone notifications.

Get it for £129.50 from Polar.

3/ New Balance RunIQ

‘Droid owner’s choice

Powered by Android Wear, the RunIQ is an all-day connected watch that can track your runs with GPS even when you leave your phone at home. A built-in Strava app seamlessly syncs your data to the popular online log.

Get it for £325 from New Balance.

4/ Apple Watch Series 2

iPhone add-on

This new model can track runs without your having to lug your phone along for the ride. Plus it stores music so you can unleash your power tunes of choice via Bluetooth headphones.

Get it for £369 from Apple.

5/ TomTom Spark3 Cardio + Music

Powered tunes

While other watches here (from Apple, New Balance and Samsung) also play music, the Spark 3 does it and saves you cash if you’re not interested in lots of battery-draining smartwatch features.

Get it for £219.99 from TomTom.

6/ Samsung Gear S3 Frontier

Phone on your wrist

The future is here – and it’s on 4G. The Gear S3 Frontier packs mobile network connectivity so you can take calls and respond to texts while on a run – without a phone.

Get it for £349.95 from John Lewis.
