Frequently Asked Questions — HYROX 8×1km Total Run (8.0 km) in 42 Min
What pace per km and per mile is needed for a 42-minute HYROX 8×1km Total Run (8.0 km)?
To finish a HYROX 8×1km Total Run (8.0 km) in 42 minutes, you must maintain an average pace of 5:15 per kilometer (8:27 per mile), which equals an average running speed of 11.43 km/h (7.10 mph) and 126 seconds per 400m track lap.
Should I run an even split or a negative split for a 42-minute HYROX 8×1km Total Run (8.0 km)?
Exercise physiology studies show a 1% to 2% negative split (running the first half ~2–3 seconds per km slower than 5:15/km and accelerating in the final third) minimizes early lactate accumulation and glycogen depletion.
