COROS Pace 3 Review: Lightweight Budget GPS Watch Still Worth It?

What It Is

The COROS Pace 3 was the entry-level running watch in COROS's lineup, aimed squarely at budget-conscious runners who wanted serious training features without paying flagship prices. It competed directly against the Garmin Forerunner 255 and Polar Pacer in the sub-$200 sport watch category. As of 2026, COROS has officially discontinued the Pace 3 in the USA and UK. The watch will continue to receive firmware updates, but it will not be restocked. If you find one new, it may be at a reduced price. COROS ran Black Friday deals knocking up to $50 off before pulling it from shelves entirely. The cheapest COROS running watch now starts at $249, which tells you the Pace 3 used to occupy an important affordable slot in their range.

Performance in the Real World

The Pace 3's dual-frequency GNSS was a genuine differentiator at its price point. Most rival watches under $200 stuck to single-band GPS, which struggles in dense urban canyons or heavy tree cover. The Pace 3 held its own in these conditions, delivering track distance readings typically within 1-2% of actual distance, competitive with the Garmin Forerunner 255 and meaningfully better than single-band alternatives at the same price.

Heart rate accuracy during steady-state efforts like easy runs and tempo intervals was solid for a wrist optical sensor. The PPG monitor performed well below threshold efforts, tracking within 3-5 bpm of a chest strap reference. Push into hard intervals or high-cadence efforts and you get the usual optical sensor lag. This is a physics limitation, not a COROS-specific failure. If you are doing serious lactate threshold or VO2max interval work and need beat-accurate HR data, pair it with a chest strap.

Sleep tracking on the Pace 3 was functional but not class-leading. It captured sleep stages and provided HRV-based recovery scores, but the granularity fell short of what Garmin's Body Battery or Polar's Nightly Recharge offer. The data was consistent enough to be useful for trend tracking over weeks, but don't expect the depth of insight you'd get from a Polar Pacer Pro or Garmin Forerunner 265.

The COROS app ecosystem is clean and uncluttered. Training load, EvoLab metrics, and structured workout support are all present and genuinely useful. The platform lacks the third-party integration depth of Garmin Connect, but for a pure running and triathlon focus, it covers the bases well. Strava sync works reliably. There are no native maps on the Pace 3. You get breadcrumb navigation only, which is a real limitation for trail runners who want proper map rendering.

One issue worth flagging: a dial failure bug on the Pace 3 was documented as recently as July 2026. COROS has been issuing firmware updates, but given the watch is now discontinued, there is a legitimate question about how long active bug support will continue. That is a real concern if you are buying one now.

Who It's For / Who Should Skip It

If you are a road runner or triathlete on a tight budget who wants dual-frequency GPS, a genuinely ultralight build, and clean training metrics, the Pace 3 was one of the best value propositions in the sub-$200 category. If you can find new old stock at a discounted price, it still makes sense for that buyer profile.

Skip it if you are a trail runner who wants onboard maps. The Pace 3 does not have them. Skip it if you rely heavily on third-party app integrations beyond Strava and TrainingPeaks. Skip it if long-term software support is important to you. A discontinued watch from a brand that moves fast through product generations is a risk. If you want a watch that is actively supported and easy to find new in 2026, the Garmin Forerunner 265 sits at a higher price but offers a deeper app ecosystem and a colour AMOLED display. For buyers with a strict budget, the Pace 3 can still earn its place if found at a steep discount, but go in with eyes open about the support horizon.

Verdict

The COROS Pace 3 was a genuinely excellent budget running watch that punched above its price with dual-frequency GPS and a featherlight build. Its discontinuation makes it a riskier buy in 2026 unless you find it at a steep discount. If long-term support matters to you, look at what is currently in production before committing.
