Station Load & Pacing Interactive Input
12.5 km/h
1km run interval split pace across all 8 running segments.
350 W
Sled mechanical work rate (50m push with standard competition sled).
24 bpm

Sports Physiology Note: In high-intensity hybrid racing (e.g. Hyrox), intense splanchnic hypoperfusion combined with elevated core body temperature and repeated abdominal intra-thoracic pressure during burpees and sled pushes creates severe gastrointestinal distress (splanchnic ischemia), an issue reported across elite endurance athletes.
