Critical Race Analysis Explained
The critical race analysis identifies key moments during a cycling race where the cyclist's cardiovascular system reaches or exceeds 90% of their maximum heart rate (HR). These moments signify significant physiological strain and help pinpoint periods of substantial effort or race-defining events.

The critical race analysis identifies key moments during a cycling race where the cyclist's cardiovascular system reaches or exceeds 90% of their maximum heart rate (HR). These moments signify significant physiological strain and help pinpoint periods of substantial effort or race-defining events.
What It Analyses:
- Critical HR Moments:
- The analysis specifically focuses on intervals where the rider's HR remains at or above 90% of their maximum for durations of at least 30 seconds. This threshold ensures only meaningful, physiologically impactful moments are examined.
- Power Before, During, and After:
- 6-minute period before the critical moment: Indicates the rider's baseline effort leading into a critical phase.
- 90-second window immediately before the critical moment: Highlights acute power surges or tactical moves leading directly into elevated HR.
- 60-second window after the critical moment: Illustrates the rider's ability to recover or sustain effort post-high intensity.
- To provide context and insight, the analysis looks at power outputs in distinct periods:
Importance of These Windows:
- 6-minute window: Helps assess baseline fatigue or strategic pacing before intense efforts.
- 90-second window: Indicates acute energy demands and the immediate trigger for cardiovascular stress.
- Critical HR Moment: Directly measures the physiological stress and cardiovascular response during high-intensity race efforts.
Metrics Explained:
- Accumulated Kilojoules (Kj) and Kj per Kilogram (Kj/kg):
- These figures provide insight into the total energy expenditure accumulated up to the critical moment, contextualising fatigue levels and overall race demands.
- Terrain Type:
Categorised as climbs, descents, or flat/rolling terrain. This contextualises how terrain influences critical cardiovascular moments and race strategy. - Efficiency (Watts per bpm HR):
Measures how effectively the rider translates cardiovascular effort (HR) into mechanical output (power). Monitoring this can reveal fatigue levels or performance changes throughout the race.
Why Understanding This Matters:
- Race Performance Insight:
Identifying precisely when and why a rider enters critical HR zones helps uncover tactical decisions, pacing effectiveness, and physiological strengths or weaknesses.
- Training Strategy:
- Understanding these moments enables tailored training. Riders can replicate critical conditions, enhance physiological adaptations, and strategically plan recovery to better handle similar efforts in future races.
