The Garmin Fenix 8 and Garmin Forerunner 965 are both among the best sports watches you can buy, and I’ve used each one to track a variety of races in the past. But I wanted to put them head-to-head over the course of a marathon to see if any major differences arose.
I used both watches at the Seville Marathon on February 23, where I clocked a new PR of 2:25:32 aided by the GPS accuracy of the Garmin watches, which helped me to pace my race.
