Delhi Half Marathon AQI & Treadmill Protocol
When particulate spikes push outdoor AQI beyond hazardous levels, transfer quality sessions indoors to protect respiratory health.
Treadmill Conversion Table
- Set treadmill incline to 1.0%–1.5% to simulate outdoor aerodynamic drag.
- Calibrate tempo sessions by target heart rate and perceived exertion rather than treadmill console speed.
- Use targeted cadence drills to maintain high stride frequency on stationary belts.
