Multi-sport athletes and adventure runners might prefer the Fenix 8's rugged build and extensive battery life.
Consider your longest typical activity. If you're training for marathons (4-6 hours), most watches handle this easily. Ultra-runners tackling 50K to 100-mile events need watches offering 30+ hours in GPS mode—the Coros Pace 3 (38 hours), Forerunner 965 (31 hours), and especially the Fenix 8 (up to 95 hours) excel here. The Polar Vantage V3's 61-hour rating is also excellent for multi-day adventures.
All five watches on this list feature dual-frequency or multi-band GPS, which dramatically improves accuracy in challenging environments like cities with tall buildings or trails under heavy tree cover. User reviews consistently confirm these watches track within 0.1-0.2 miles over marathon distances when compared to measured courses. For heart rate accuracy during intense intervals, consider pairing any watch with a chest strap—even the best optical sensors can struggle with rapid changes.
Decide whether you want a training tool or a daily smartwatch. The Coros Pace 3 and Polar Vantage V3 focus on athletics with limited smart features—no music streaming, contactless payments, or extensive app ecosystems. The Garmin watches offer middle ground with music storage, Garmin Pay, and notification support. The Apple Watch Ultra 2 provides complete smartphone functionality but requires daily charging.
Training Load measures the physiological impact of your workouts, typically expressed as a score based on duration, intensity, and heart rate data. Acute Load (last 7 days) compared to Chronic Load (last 28 days) helps identify whether you're building fitness sustainably or risking injury through overtraining. The Garmin watches show this as Training Load Ratio, while Polar provides Training Load Pro with clear visual guidance.
