sport.marathon-pacing-splits Calculator
Generates per-kilometre splits for a target marathon time using an optional positive split strategy, and shows cumulative time at each 5 km mark. Even-splitting is the gold standard for most runners; even 2–3% positive split often causes late-race collapse.
Inputs
Target Time Hr
Duration of the process. Make sure units match the rate inputs (seconds, minutes, or hours).
Positive Split Pct
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
Results
average pace (min/km)
The arithmetic mean -- sum divided by count.
first half time
The computed duration or time value.
second half time
The computed duration or time value.
even split target
Sample size or count used in the calculation.
Kipchoge 2:00:35 pace
Reference formula or conversion factor shown for context.
positive split risk
Overall risk level based on the computed score or classification. Higher risk may call for mitigating actions or additional review.
