Understanding Running Pace and Split Calculations

Your running pace is the time it takes to cover a specific distance, usually expressed in minutes per mile or minutes per kilometer. The relationship is defined by:

• **Pace:** $\text{Pace} = \text{Time} / \text{Distance}$
• **Time:** $\text{Time} = \text{Pace} \times \text{Distance}$
• **Distance:** $\text{Distance} = \text{Time} / \text{Pace}$

Metric vs. Imperial Splits

Converting running speed metrics requires converting between miles and kilometers:

• 1 mile is exactly $1.609344$ kilometers.
• 1 kilometer is approximately $0.621371$ miles.
• To convert minutes/mile to minutes/kilometer, divide your mile pace by $1.609344$.
• To convert minutes/kilometer to minutes/mile, multiply your kilometer pace by $1.609344$.
