COROS PACE 4

The COROS PACE 4 is a lightweight GPS running watch with a 1.2-inch AMOLED touchscreen. COROS announced it on 10 November 2025 from its base in Irvine, California, with sales starting the same day on its own website and at selected retailers worldwide, and it set the United States price at $249. The watch is the successor to the PACE 3 and is aimed at runners, triathletes and cyclists who want simple, fast tools rather than a smartwatch full of apps. This page is a specification-and-information review based on the published specifications and manufacturer information, so every battery, accuracy and training claim below is COROS's own and is not a measurement made here. The sections cover where the watch sits in the lineup, its design and display, positioning and sensors, the training features, the battery, who it suits and the compromises.

Place in the lineup

COROS describes the PACE 4 as an AMOLED GPS watch that wears easily all day and night, and it treats the model as the entry point for runners who want a modern display without a bulky case. Within its own range, COROS compares it directly with the PACE 3 and the PACE Pro: its battery claim is 16 GPS hours more than the PACE 3 and 3 hours more than the PACE Pro, according to the labels on its product page, although the page does not spell out exactly which test mode those comparisons use. The family also includes versions with an aluminium bezel, called Black Crystal and Cloud White, next to the standard version, which has a fibre-reinforced polymer bezel.

Among competitors, the closest rivals are the other running-first watches in this price bracket. The Garmin Forerunner 170 and the Garmin Forerunner 70 are the obvious Garmin comparisons, and the Amazfit Cheetah 2 Pro approaches the same runner from a higher, titanium-and-sapphire price tier. A direct side-by-side with the Garmin is on the page COROS PACE 4 vs Garmin Forerunner 170.

Design and display

COROS lists the case thickness as 11.8 mm and the weight as 32 grams with the nylon band or 40 grams with the silicone band. At 32 grams the watch is very light for a GPS sports watch. The case diameter is not given on the product page, so it is not stated here. The design is low-profile and two-tone, with a tapered display edge and interchangeable bands: silicone, which COROS says is quick to fasten and easy to dry, and nylon, which is described as breathable, sweat-wicking and easy to adjust. The standard version can be fitted with any colour of either band.

The screen is a 1.2-inch AMOLED touchscreen with automatic brightness adjustment. COROS states that its resolution is 164 percent higher than the PACE 3 but gives no pixel count, so the true sharpness cannot be checked from the specification. AMOLED panels produce deep blacks and strong contrast, which helps with legibility in bright sun and with a vibrant watch face, but they typically consume more power than the simpler displays used in many endurance watches. The product page does not state the glass type or the water-resistance rating, so neither is claimed here; check COROS's site before buying if swimming matters to you.

The controls combine three kinds of input: a touchscreen, two buttons and a tactile digital dial. There is also an Action Button that switches between data screens, media controls, breadcrumb navigation and Voice Pins. A physical dial and buttons are the right choice for running in the rain or with sweaty hands, when a touchscreen alone is unreliable, and the touchscreen is there for quick menus and scrolling.

Positioning and sensors

For positioning, COROS lists All-Systems and Dual-Frequency satellite modes, and says new satellite modes lock on faster and with higher accuracy. Multi-system, dual-frequency tracking uses more than one satellite network and more than one radio band, which can help in tall cities and under trees, but the product page gives no detailed list of satellite networks or bands. The battery figure for GPS is stated for the All Systems (High) mode, so the most accurate tracking setting is also the one that sets the headline 41-hour claim.

The optical heart rate sensor is redesigned with larger LEDs and a more secure fit, and COROS says it reduces spikes and drops in readings. Wrist-based heart rate measurement is known to be difficult during fast intervals, so this claim is worth checking in independent tests. A built-in microphone lets you record training logs, voice memos and Voice Pins hands-free. The product page does not list other sensors, music storage or connectivity details, so none are described here. For charging, the watch uses a USB-C charging adapter that needs only one cable, but the cable itself is not included.

Training and health features

The running toolset is the core of the watch. COROS lists running fitness scores and tests, race predictions, personalised marathon plans, a Virtual Pacer, Effort Pace and real-time activity alerts. Virtual Pacer helps you hold a target speed, while Effort Pace is meant to guide you by effort rather than by speed when hills or wind distort your pace. Recovery and health features include HRV, sleep and recovery time tracking, and menstrual cycle tracking. The watch can also skip tracks or podcasts and adjust volume from the wrist, meaning it controls media played on your phone rather than storing music, as far as the published material says.

These tools make the watch a good fit for structured training. The announcement does not discuss subscriptions either way, so that point is unconfirmed. COROS also reports that The New York Times Wirecutter named the PACE 4 its best overall running watch for 2026. That is an endorsement quoted by the company, and it should be read as one reviewer's view rather than as proof of superiority.

Battery

COROS claims up to 41 hours of GPS use in All Systems (High) mode and up to 19 days of daily use on one charge. Both figures are the company's, depend on features such as music, backlight and navigation, and COROS notes that actual results vary and that lithium-ion batteries degrade over time. The capacity in mAh is not published. Forty-one GPS hours covers many long runs between charges, and 19 days of regular use is generous for an AMOLED watch, though always-on display behaviour and notification load will change that in real life. A sensible expectation is that heavy GPS users will charge about weekly.

Who it is for

• Runners, triathletes and cyclists who want a very light watch with a bright AMOLED screen.
• Marathon trainees who want race predictions and personalised plans on the wrist.
• Users who value physical controls and a digital dial more than a touch-only interface.
• Buyers who want long battery life from a watch that weighs only 32 grams.

Compromises

• The product page gives no water-resistance rating, glass type, storage size or connectivity list, so these cannot be confirmed from official material.
• AMOLED screens use more power than simple displays, and the 41-hour and 19-day figures are best-case claims.
• Music is limited to controlling media from the watch, according to the published description.
• The USB-C charging cable is not included in the box.
• The $249 price applies to the standard model; the aluminium-bezel versions may cost more, and no price for them is listed here.

In short, the PACE 4 is a light, focused running watch with a modern AMOLED display, solid claimed battery life and a practical set of training tools. It is best for runners who want performance without extra bulk. For other watches ranked by their published specifications, see the rankings page.
