Marathon Pace Calculator
Calculate the required pace per km and per mile for your marathon time goal.
The Marathon Pace Calculator determines the pace you need to maintain throughout 42.195 km (26.2 miles) to hit your target finish time.
Enter your target hours and minutes, and the calculator computes the required pace per kilometer and per mile. It also estimates your half-marathon split time and 5K split time assuming even pacing.
Running an even pace is the most efficient marathon strategy. If your target is 4 hours, you need approximately 5:41 per km or 9:09 per mile consistently for the entire race.
