Garmin Forerunn er 645 Music £309, garmin.com

This does everything: GPS for running and cycling, heart rate tracking, VO2 Max, intensity monitoring and even acting as an MP3 player. Expect four days of use between charges.

Garmin Forerunn er 630 £309, garmin.com

The official price is similar but thanks to discounting this is often much cheaper than the 645. There’s no heartrate or music but you do get GPS, reliable tracking and ace running metrics.

Garmin Forerunn er 235 £175, Garmin.com

The Forerunner 235 is the best value running and general fitness watch around, offering more than enough data for most runners without the expense of slightly more powerful models.

TomTom Spark 3 Cardio + Music £219, tomtom.com

Like the Forerunner 645 this can soundtrack your runs, and it’s as good for gym and zone training as it is for running. The heart-rate monitoring can be flaky but it’s a solid choice.
