Outcome
Time-trial performance
Practical performance outcome used in many studies: closer to racing than lab-only metrics.
What to do first
- • Use pacing rules and negative-split practice in training.
- • Add one weekly session that targets your event intensity.
- • Practice race-day fueling and hydration on key sessions.
