In the end, this product comparison should make it clear that the Coros Pace 2 actually trumps the Garmin Forerunner 55 as a sports watch. It has a very compelling unique selling point for runners (running power from the wrist), it’s an affordable option for triathletes, and it offers all the most important sports modes for most people.
On top of all this, it manages to fit all these extra features into a package that is basically the exact same price.
With that being said, if you prefer the Garmin brand and running is your primary sport, the Forerunner 55 is a very good choice, offering plenty of running features in a sleek and attractive design.
