Pace Calculator

How to use this calculator

1. Enter distance plus your hours, minutes, and seconds.
2. We convert the total time to minutes, divide by distance, and return pace per mile plus average mph.
3. Use the pace to set training targets or compare to race goals.

Inputs explained

Distance

Total distance of your run/walk in miles. Convert km to miles if needed.

Hours/Minutes/Seconds

Finish time broken into standard units for accuracy.

When to use it

• Checking race pace from a recent 5K, 10K, or half marathon.
• Setting training paces for long runs or intervals.
• Comparing how different finish times translate into mph for treadmill settings.

Tips & cautions

• If you run in kilometers, convert distance to miles or run the math twice to get both mile and km paces.
• Round pace to the nearest second for workouts; races benefit from exact pacing.
• For negative splits, pair this with lap data from your GPS watch.
• Assumes constant pace across the whole distance—splits aren’t modeled individually.
• Does not adjust for elevation gain, terrain, or weather.
• Distance accuracy matters; GPS errors can skew pace slightly.

FAQs

Can I enter kilometers?

Convert distance to miles or run the calculation twice for both mile and km pace.

Does it support negative splits?

This calculator averages the entire effort. Use GPS splits for per-mile breakdowns.
