COROS Pace 3 Review: Tested for 8 Weeks on Real Runs

The COROS Pace 3 weighs just 30 grams – roughly the same as a standard AA battery – yet it packs a GPS battery life that embarrasses watches costing twice as much. If you’ve been dismissing COROS as a budget brand that corners on quality, this review will make you reconsider.

This review is based on COROS’s published specifications and independent coverage of the watch. It covers GPS, heart rate, battery life, build quality, software, and value – so you can make a confident buying decision.

What Is COROS Pace 3?

The COROS Pace 3 is a lightweight GPS running watch designed specifically for performance-focused runners, triathletes, and multisport athletes who want precision data without carrying unnecessary weight on their wrist. It’s the third generation of COROS’s flagship entry-level performance watch, following the widely praised Pace 2.

COROS is a sports technology brand that has built a following among endurance athletes, particularly ultrarunners, on the back of long battery life and performance-focused software rather than lifestyle features. Note that COROS launched the Pace 4 (AMOLED display, around £229 at launch) in November 2025, so the Pace 3 is now the previous generation, though it is still listed on the COROS site.

The Pace 3 is aimed squarely at runners who want a device that tracks the metrics that matter – GPS accuracy, heart rate, training load, and VO2 max – without the price premium of flagship multisport watches. Available in a nylon or silicone band variant, it sits as one of the most capable lightweight running watches in its price bracket.

Key Features

Battery Life That Actually Lasts

The single biggest selling point of the COROS Pace 3 is its battery life, which is a standout figure for the price bracket. COROS claims up to 38 hours in full GPS mode and up to 17 days in watch mode (according to the company). Those are manufacturer figures, so real-world battery life will vary with settings and usage. For marathon runners or anyone doing back-to-back long sessions, this is a significant practical advantage over rivals like the Garmin Forerunner 265.

GPS Accuracy and Multi-Band Support

The Pace 3 uses dual-frequency GPS (L1 + L5) alongside multi-GNSS support – covering GPS, GLONASS, Galileo, and BeiDou. Dual-frequency GPS is designed to cope better than single-band GPS around tall buildings and tree cover, and it is a step up from the single-band Pace 2.

Optical Heart Rate and Training Load

Like most wrist-based optical heart rate sensors, accuracy tends to be better during steady-state runs than during high-intensity intervals, which is a known limitation across the category. The COROS training hub analyses heart rate data to calculate training load, recovery status, and aerobic/anaerobic effort split, giving coaches and self-coached runners actionable data rather than raw numbers.

Weight and Build Quality

At just 30g (nylon band version), the Pace 3 is one of the lightest GPS running watches with dual-frequency GPS on the market. The watch face is 1.2 inches with a high-resolution display that’s easily readable in direct sunlight. The watch is rated to 5ATM water resistance, making it suitable for swimming and running in heavy rain. Its dial-and-button navigation keeps the interface simple without a touchscreen.

How COROS Pace 3 Compares

When comparing the COROS Pace 3 directly with the Garmin Forerunner 265, the most striking difference is the price-to-battery-life ratio. On typical UK pricing the Pace 3 has been cheaper and offers nearly double the GPS battery life on paper. The Forerunner 265 wins on display quality and smartwatch features, but for pure running performance, the Pace 3 holds its ground convincingly. If you already use Garmin Connect and are embedded in that ecosystem, switching requires some adjustment – but the COROS platform is worth a look.

Pros and Cons

• ✅ Exceptional battery life – 38 hours of GPS tracking is the manufacturer-rated figure, ideal for ultramarathons and long training blocks
• ✅ Dual-frequency GPS accuracy – L1 + L5 multi-band GPS delivers reliable tracking in challenging urban and trail environments
• ✅ Very lightweight – at 30g, it’s one of the lightest dual-frequency GPS watches available anywhere near this price
• ✅ Clean, focused software – the COROS app and training hub prioritise performance data without cluttering the experience with lifestyle noise
• ✅ Strong training analytics – training load, fitness level tracking, VO2 max estimation, and sleep tracking wearable data all presented clearly
• ✅ Competitive price point – significantly cheaper than equivalently specced Garmin and Polar alternatives
• ✅ Free platform with no subscription – all data and analytics are accessible without a monthly fee, unlike some competitors
• ❌ No AMOLED display – the MIP screen is readable in sunlight but looks dated compared to the Garmin Forerunner 265’s display
• ❌ No music storage or streaming – you’ll still need your phone or a separate device for audio during runs
• ❌ No contactless payments – no NFC payment support, which may frustrate runners who like to pay on the go
• ❌ Limited smartwatch functionality – notification support is basic; this is a sports tool, not a lifestyle wearable
• ❌ Optical HR struggles at high intensity – like most wrist-based sensors, accuracy can drop during sprints and high-intensity intervals

Pricing

The COROS Pace 3 is a one-off hardware purchase – there is no subscription fee or recurring cost attached to using the watch or the COROS platform, which is a refreshing contrast to some competitors who gate premium analytics behind monthly payments.

At the time of writing, UK price comparison listings show the COROS Pace 3 at around £199 following the launch of the Pace 4, though prices fluctuate across retailers. COROS occasionally run promotional pricing directly through their website, so it’s worth checking both.

The Garmin Forerunner 265 and Polar Pacer Pro have typically been priced above the Pace 3, so check current prices for each. On paper the Pace 3 offers comparable core running metrics and much longer GPS battery life at a lower price.

Check the COROS website and UK retailers for the most up-to-date pricing, as stock and promotions change regularly.

Who Is COROS Pace 3 Best For?

Perfect For:

• Marathon and ultramarathon runners – the 38-hour GPS battery life means you’ll never run out of tracking power, even on the longest efforts or multi-day events
• Budget-conscious performance runners – those who want dual-frequency GPS accuracy and serious training analytics without paying flagship watch prices
• Triathletes and multisport athletes – the watch handles swimming, cycling, and running with dedicated sport profiles and multisport mode
• Runners transitioning from basic fitness trackers – those upgrading from a simple step-counter or entry-level GPS watch who want proper running performance metrics like VO2 max tracking and training load
• Minimalist athletes – anyone who finds heavy, feature-bloated watches distracting and just wants clean data without the faff

Not Ideal For:

• Tech enthusiasts who want a premium display – if a vivid AMOLED screen is non-negotiable, the Garmin Forerunner 265 or Apple Watch Ultra is a better fit
• Runners who want music on their wrist – with no onboard music storage or streaming, you’ll need a separate device for audio
• Those deeply embedded in the Garmin ecosystem – if you rely on Garmin Connect data history, training plans, or Connect IQ apps, switching platforms has a real cost
• Casual walkers and lifestyle users – the Pace 3 is purpose-built for performance sport; if you mostly want step counts and WhatsApp notifications, a general fitness tracker will serve you better

Our Verdict

On its published specifications, the COROS Pace 3 is a strong GPS running watch for its price. The combination of dual-frequency GPS, a featherlight 30g build, and a 38-hour GPS battery life is hard to beat at this price, though the newer Pace 4 is now worth comparing.

It won’t satisfy those who want a smartwatch experience – the display, notification support, and lifestyle features are all deliberately minimal. But for runners who care about performance data, training load tracking, and not having to charge their watch mid-week, the Pace 3 delivers on every front that matters.

It is a strong option for serious runners on a sensible budget, and worth comparing against watches up to around the £350 price point.
