Calculate Wind-Adjusted Pace
Quick Presets
How it works
Adjusted Pace = Base Pace × (1 + (Wind Speed / Base Running Speed) × Wind Factor). We estimate how wind affects your running speed and adjust your pace or time accordingly. Wind factors: Headwind=0.5, Tailwind=-0.3, Crosswind=0.1.
Inputs explained
- Base Pace
- Your normal running pace without wind.
- Wind Speed
- The speed of the wind in km/h or mph.
- Wind Direction
- Headwind (into wind), Tailwind (with wind), or Crosswind (side wind).
- Race Distance
- The total distance of your run or race.
Example
Base Pace: 5:00 min/km, Wind: 20 km/h Headwind, Distance: 10k
- Base Running Speed: 12 km/h (60 / 5)
- Wind Factor: 0.5 (headwind)
- Adjusted Pace: ≈5:50 min/km
- Time Impact: ≈50 seconds slower for 10k

Tips & notes
- Headwinds: Significantly slow you down, especially at higher speeds.
- Tailwinds: Can provide a small boost, but less than headwinds slow you.
- Crosswinds: Have minimal effect on pace but can affect stability.
- Course strategy: Conserve energy when running into headwinds.
FAQs
It creates air resistance, which can slow you down (headwind) or speed you up (tailwind).
It varies by fitness level. 5-6 min/km is a common goal for recreational runners.
