I ran over 1,500 miles and completed the London Marathon with the Coros Pace 4 to see if this $249 sports watch could actually beat my Garmin, and its dual-band GPS accuracy and battery life left me seriously impressed

Coros Pace 4.

I’ve been impressed by the Coros Pace line of watches ever since the original launched in 2018, and the Coros Pace 4 is the best version yet.

I raved about the Pace 4 in my original review of the watch, and it’s stayed on my wrist for the six months since, while I trained for and ran the London Marathon.
