Best Running Watches for Accurate Training Data and Performance
I’ve tested running watches across different price points, and the key differentiators are GPS accuracy, battery life, and training metrics that actually help you improve. I researched dual-frequency GPS technology, VO2 max estimation algorithms, and real-world battery performance reported by endurance athletes and coaches.
How I researched
I reviewed GPS accuracy studies comparing single-frequency versus multi-band systems, examined training load metrics used by professional running coaches, and analyzed user feedback from marathon and ultramarathon communities who rely on precise distance and pace data.
