Pace Conversion Formula:
From: | To: |
The pace conversion formula allows runners to estimate their performance at different distances based on their known pace at a reference distance, accounting for the fact that running speed doesn't scale linearly with distance.
The calculator uses the pace conversion formula:
Where:
Explanation: The formula accounts for the fact that runners slow down slightly when running longer distances, with the exponent k modeling this non-linear relationship.
Details: Pace conversion helps runners set realistic goals for races of different distances, plan training sessions, and estimate race times based on shorter training runs.
Tips: Enter your known pace (minutes and seconds per km), the distance you ran that pace at, the new distance you want to predict for, and the exponent (1.06 is a good default).
Q1: What's a typical value for the exponent k?
A: Research suggests k ≈ 1.06 is appropriate for most runners, though it may vary slightly between individuals.
Q2: How accurate is this conversion?
A: It provides a good estimate but actual performance depends on factors like training specificity, terrain, and weather conditions.
Q3: Can I use this for very short or very long distances?
A: The formula works best for distances between 800m and marathon (42.2km). Extreme distances may require different exponents.
Q4: Why does pace change with distance?
A: Longer distances require more energy conservation and involve greater fatigue, while shorter distances allow for more anaerobic contribution.
Q5: How should I adjust for trail running?
A: For trail or hill running, you may need to use a larger exponent (1.07-1.10) to account for the additional difficulty.
