How to Use This Pace Calculator
- Select a popular race distance (such as 5K, 10K, Half Marathon, or Full Marathon) from Preset Race Distance, or enter a custom length in Distance.
- Choose your measurement standard in Unit (Miles or Kilometers).
- Enter your goal duration in Target Finish Time (Hours, Minutes, Seconds).
- Click “Calculate Pace & Race Splits” to generate your required per-mile or per-kilometer pace and projected finish times for other standard race distances.
The Pace Formula
Running pace expresses time elapsed divided by distance covered:
Pace = Total Time in Minutes / Total Distance
Example: 105 minutes / 13.1 miles = 8.015 minutes per mile (8:01 min/mi pace).
Example: 105 minutes / 13.1 miles = 8.015 minutes per mile (8:01 min/mi pace).
Frequently Asked Questions (FAQ)
What is a good running pace for a half marathon?
Average half marathon finish times typically range between 1:50:00 and 2:10:00, which corresponds to roughly an 8:20 to 9:55 min/mile pace (5:10 to 6:10 min/km).
How do I convert min/mile pace to min/km pace?
To convert pace from minutes per mile to minutes per kilometer, divide your per-mile pace in seconds by 1.60934. For example, an 8:00 min/mi pace equals approximately a 4:58 min/km pace.
What are negative splits in long-distance running?
A negative split means running the second half of a race faster than the first half. It is widely considered the optimal pacing strategy for marathon and half-marathon personal records.
