A pace calculator helps runners and cyclists convert between pace, time, and distance. Whether training for a 5K or planning a marathon, knowing your target pace helps you set realistic goals and maintain consistent effort throughout a race.

Select what you want to find: Pace, Time, or Distance. Enter the two values you know (e.g. time and distance to get pace). Choose your units (e.g. min/mile, min/km, or speed in mph/km/h). Click Calculate. The calculator solves for the missing value, useful for planning runs or bike rides.

Examples

Calculate Pace for a 5K

If you run 5K in 25 minutes, your pace is 5:00 per kilometer or 8:03 per mile.

Common Race Distances and Target Paces

Race	Distance	Beginner Pace	Intermediate Pace	Advanced Pace
5K	3.1 miles	12:00-14:00 min/mi	9:00-11:00 min/mi	6:00-8:00 min/mi
10K	6.2 miles	12:30-15:00 min/mi	9:30-11:30 min/mi	6:30-8:30 min/mi
Half Marathon	13.1 miles	13:00-15:00 min/mi	10:00-12:00 min/mi	7:00-9:00 min/mi
Marathon	26.2 miles	13:00-16:00 min/mi	10:00-12:30 min/mi	7:00-9:30 min/mi

Frequently Asked Questions

What is a good running pace?

Pace varies by experience. Beginners often start at 10-12 mins/mile, while competitive runners may maintain sub-7 mins/mile.

Key Terms

Pace: The time it takes to cover a unit of distance, typically expressed as minutes per mile or minutes per kilometer.
Negative Split: Running the second half of a race faster than the first half, generally considered an optimal pacing strategy.
Tempo Run: A sustained run at a comfortably hard pace, typically 25-30 seconds per mile slower than 5K race pace.
Splits: The time for each segment of a race, such as each mile or kilometer.

Quick Tips

•Start races slightly slower than your target pace — you can always speed up in the second half.
•Train at different paces: easy runs build endurance, tempo runs build speed, intervals build power.
•Use pace per mile or pace per km consistently to avoid confusion in race planning.
•Factor in 5-10% slower pace for trail running compared to road running at equivalent effort.
