GPS Running Watches / COROS
COROS PACE 4 (silicone band)
Multiband GPS and 31 hours of it for $249 — the value benchmark of the category.
Overall score 7.8/10
Pros
- + Dual-frequency L1+L5 GNSS at $249 — the single biggest accuracy upgrade you can buy at this price
- + 31 h in the most accurate GPS mode still beats what most $500 AMOLED watches manage
- + 32 g on the nylon band; you forget it is there on a long run
- + No subscription anywhere in the COROS ecosystem, and .FIT files sync free to Strava and TrainingPeaks
- + DC Rainmaker found the optical HR 'spot-on' through intervals — unusual for a $249 watch
Cons
- − No offline maps at all — breadcrumb trails only, which is a real limitation off-road
- − No ANT+, so ANT+-only power meters and older chest straps will not pair
- − Music is sideloaded MP3 only; there is no Spotify, no streaming, no phone-music control
- − Always-on display costs 13 of the 19 claimed smartwatch days and 10 h of GPS time
- − Training Load resets every Monday rather than rolling, which DC Rainmaker notes does not match recovery physiology
COROS PACE 4 (silicone band) review: what the specs say
Multiband GPS and 31 hours of it for $249 — the value benchmark of the category. At $249, COROS's 2025 model sits among the cheapest we cover — the GPS Running Watches we compare run from $249 to $1,199.99. It scores 7.8/10 overall, calculated from published specifications across 8 categories rather than from a subjective impression.
Its strongest showing is Value at 9.4/10 — what the watch delivers per dollar against everything else in the comparison at the moment of purchase.. The weakest is Navigation & Maps at 3.5/10, which is the trade-off to weigh before buying: if that is the specification you care about most, one of the alternatives below will serve you better.
Worth knowing before you buy: no offline maps at all — breadcrumb trails only, which is a real limitation off-road; and no ANT+, so ANT+-only power meters and older chest straps will not pair. Every specification on this page comes from COROS's own documentation or a verified retail listing — where a figure is not published, the table says so rather than estimating it.
