COROS Pace 4 vs Garmin Forerunner 170: Best Value GPS Watch for Runners

What do I need to buy

Selecting the right GPS watch requires a clear understanding of your training volume and performance goals. Before committing to the COROS Pace 4 or Garmin Forerunner 170, ensure you have the necessary accessories to complement your tech. For marathon training, prioritise high-quality gear to prevent injury and improve visibility. We recommend investing in a Sundried reflective running vest for low-light safety, a durable phone armband for emergency connectivity, and moisture-wicking anti-blister running socks to keep your feet in prime condition during long-distance efforts.

The COROS Pace 4 enters the market with a lightweight nylon chassis, prioritising weight reduction and comfort during high-intensity intervals. Conversely, the Garmin Forerunner 170 utilises a traditional high-grade silicone strap and a robust polymer casing, offering a familiar, tactile experience that many long-term Garmin users have come to expect. Both watches serve as essential tools for data-driven athletes looking to monitor their physiological metrics.

Navigation philosophies differ significantly between these two titans. COROS employs a signature digital crown, allowing for seamless scrolling through data screens even when wearing thick winter gloves. Garmin maintains its commitment to a multi-button layout, which provides a definitive, clicky feedback mechanism that is often preferred by athletes who find touchscreens or rotating crowns finicky during rainy weather or sweaty sessions.

Optical heart rate accuracy remains the cornerstone of modern athletic tracking. Both devices utilise updated sensors that monitor blood flow through the wrist with impressive precision. However, for those performing high-intensity interval training, both manufacturers recommend pairing these watches with a dedicated chest strap to eliminate potential cadence lock issues.

Training load algorithms have become the primary battleground for these brands. COROS focuses on its proprietary EvoLab system, which offers an analytical deep dive into your fitness level, fatigue, and recovery status. Garmin counters with its long-established Training Status and Readiness metrics, which draw from a massive dataset to provide a comprehensive view of your cardiovascular health.

Why Should I invest?

Investing in a dedicated GPS watch is the single most effective way to quantify your progress. Beyond simple distance tracking, these devices act as a coach on your wrist, providing real-time feedback on your pacing, cadence, and vertical oscillation. For a runner aiming to break a personal best, the cost of these watches is negligible compared to the value of avoiding overtraining injuries through data-informed recovery.

The price-to-performance ratio of these specific models is unparalleled. Both the Pace 4 and the Forerunner 170 occupy the 'sweet spot' of the market, offering sophisticated GNSS connectivity that maintains signal strength in dense urban centres or under thick tree canopies. You are essentially paying for the accuracy of your training data, which ensures every kilometre logged contributes meaningfully to your aerobic base.

What are the press saying?

Early industry reports are largely positive, with journalists noting that the COROS Pace 4 has made massive strides in battery efficiency, often outlasting the Garmin in extended GPS modes. Critics have praised the digital crown for its intuitive feel but have noted that the Garmin Forerunner 170 holds a slight edge in terms of ecosystem integration, specifically regarding social connectivity and third-party app syncing.

What are the review sites saying?

Public forums and verified review sites suggest a clear divide in user preference. Many users report that the Garmin ecosystem is more intuitive for beginners, while the COROS community frequently cites the lack of a subscription model as a decisive factor in their purchase. Rumours continue to circulate regarding a future firmware update for the Pace 4 that may introduce advanced navigation features, though COROS has yet to confirm these claims officially.

Ultimately, the decision rests on your personal preference for interface design and ecosystem loyalty. If you value a sleek, lightweight design and a robust, free training platform, the COROS Pace 4 is a formidable contender. If you prefer a proven, reliable button-led architecture and a massive, interconnected network of fellow runners, the Garmin Forerunner 170 remains the gold standard for value-driven performance.

Regardless of your choice, consistency is the key to running success. Use your new watch to track your weekly mileage, monitor your recovery, and stay within your target heart rate zones. By pairing your device with proper gear like Sundried reflective apparel and moisture-wicking socks, you are setting yourself up for a successful racing season.
