Wrist-based running power is welcomed as a surprisingly advanced training tool at this price, giving runners another way to manage effort and work on form.

Running power support was strongly praised, especially by triathlon and trail-focused reviewers who value native power for pacing and power-zone training.

Pros: recovery insights, heart rate accuracy

Cons: mapping and navigation, value for money

Pros: GPS accuracy, value for money

Cons: battery life, smartwatch features

Running power support was useful for one reviewer, but others questioned related metric reliability or found the calculation too different to evaluate.

Cons: band quality, smartwatch features

#11 Garmin Forerunner 255S
3.0

Running power support was useful in concept but limited by the need for an external Garmin sensor.

Pros: value for money, battery life

Cons: menu navigation, user interface

#12 Garmin Forerunner 955
