Race Time Calculator

See how long it will take to reach the finish line by multiplying course distance by your goal pace. The calculator outputs race time in minutes so you can back into splits, hydration reminders, and nutrition breaks.

Enter the course length in kilometers. Convert miles to kilometers by multiplying by 1.609.
Average minutes per kilometer you plan to hold. Use recent training splits for realistic pacing.

For general fitness planning only; actual race times may vary.

Examples

  • 10 km at 4.45 min/km ⇒ 44.5 minutes (about 44 minutes 30 seconds)
  • 21.1 km half marathon at 5.3 min/km ⇒ 111.83 minutes (1 hour 51 minutes)

FAQ

Does this account for elevation changes or terrain?

No. Enter a more conservative pace if the course includes hills, trails, or extreme weather.

Can I enter the distance in miles?

Convert miles to kilometers by multiplying miles by 1.609 before entering the value.

What if I accidentally use a zero pace?

A pace of zero minutes per kilometer will return zero time. Use your recent training pace or race goal instead.

How can I break the result into hours, minutes, and seconds?

Divide the total minutes by 60 for hours, then convert the remainder into minutes and seconds to match race timing mats.

Additional Information

  • Multiply the decimal portion of the result by 60 to convert remaining minutes into seconds for race clocks.
  • The formula assumes a steady pace; adjust your target to account for hills, heat, or terrain.
