Is Suunto Run 2 as Accurate as the Polar H10?

In this video, I tested the heart rate accuracy of the Suunto Run 2 directly against the Polar H10 chest strap to see if a wrist-based optical sensor can truly keep up with the gold standard. I took both out on the road to put them through their paces across steady-state miles, tempo intervals, and sudden spikes in heart rate. We’ll look side-by-side at the real tracking graphs, latency differences, and overall consistency so you can decide if you can finally ditch the chest strap for your daily training. 0:00 - Introduction & Test Setup 0:30 - Polar H10 Baseline & Optical vs ECG 1:06 - Key Testing Objectives (Lock-on & Movement) 1:50 - Test 1: 3.6-Mile Steady Outdoor Run 2:13 - Test 2: 11.5-Mile Steady Outdoor Run 3:37 - Test 3: Strength training 4:26 - Test 4: HIIT Training 20/10 5:20 - Test 5: HIIT Training 4 by 4 6:20 - Conclusion Suunto Run 2 GPS Watch Polar H10 Heart Rate Monitor
