Race reports and analysis built from heart rate, calorie burn, cadence, and recovery data captured during real HYROX races. Every chart cites its source. Every conclusion shows its data.
1,157 heart rate samples from a 2:01:06 finish, broken down by all 16 segments. 92% of the race spent at threshold or above. Five charts covering zone distribution, per-segment effort, drift, and post-station recovery — built from one athlete’s Apple Watch hardware and the official HYROX timing system.
