Garmin Forerunner 255 review | Tom’s Guide

It’s hard to improve on an already great running watch, so when Garmin announced the Forerunner 255, it was a case of finding out what’s new, and whether it was worth it. The answer is a big yes, in a small package. Garmin has packed a lot of new features into the Garmin Forerunner 255, and I’ve been putting it to the test to find out more.

I’ve loved the smaller 42mm watch face (the Forerunner 255 comes in two sizes — 42mm and 46mm) and the ability to load music onto my watch and leave my phone at home. (The watch comes in two variants — with music, and without.). It’s also now got multisport profiles, upgrading the Forerunner 255 from a running watch to a watch that could get you through your training for a triathlon.
