When running, do you prefer a screen or a hands-free experience?

Runners face a choice: a watch with a screen shows real-time pace but is heavy and noticeable; a ring is unobtrusive but doesn’t display real-time data. Consideration: It depends on your running goals.

10 Half-Marathon Real-World Comparisons

I wore the Garmin Forerunner 265 on my left hand and the Ultrahuman Ring on my right hand for 10 half-marathon tests.

Heart Rate Accuracy: The average deviation from a chest strap was 2.1 bpm for the watch and 3.4 bpm for the ring; the ring was slightly less accurate but still within an acceptable range.

GPS: The ring lacks standalone GPS and must rely on a smartphone; its track accuracy is inferior to that of a watch.

Real-Time Feedback: The watch displays pace, helping you control your rhythm; the ring only shows data after the run is complete.

Comfort: The ring wins hands-down, especially during long-distance runs, where the watch’s weight becomes increasingly noticeable.

In a survey of 10 runners’ preferences, 100% of elite runners aiming for personal bests chose the watch; among casual joggers, 60% preferred the ring-and-phone combination.

The American Running Association recommends: Use a GPS watch for competitive races, and the ring for fitness runs and daily monitoring.
