Weather Pace Compensator
Adjust the target pace for heat and humidity using the dew-point Stress Score.
| Stress Score (°F + °F) | Slowdown | Guidance |
|---|---|---|
| ≤ 100 | 0% | Ideal — run the planned pace |
| 101–120 | 0.5–1.0% | Negligible; monitor hydration |
| 121–140 | 1.5–3.0% | Noticeable; announce the adjusted pace at the corral briefing |
| 141–160 | 3.5–5.0% | Hard; adjust pace and increase fluid intake |
| 161–180 | 6.0–8.0% | Very hard; organizer to consider revised targets |
| > 180 | 10% + | Unsafe to pace for time — run for safety only |
