How We Calculate This
This running pace calculator uses established formulas and industry-standard data to provide accurate estimates.
- Enter your specific values into the calculator fields above

These calculations are estimates based on standard formulas. For critical decisions, always consult a qualified professional.
How to Convert Oven Recipes to Air Fryer
This calculator works in three modes: find your pace from distance and time, find your finish time from distance and pace, or find your distance from pace and time.
The basic rule:
- Pace mode: Enter distance and finish time to get your per-mile and per-km pace
- Time mode: Enter distance and target pace to get your projected finish time
- Distance mode: Enter pace and time to find how far you ran
The calculator also generates a mile-by-mile splits table so you can plan your race pacing strategy. Even pacing (running the same pace throughout) is the most efficient strategy for most runners.

Frequently Asked Questions
What is a good running pace for beginners?
Most beginners run between 10:00-13:00 per mile (6:15-8:00 per km). A comfortable conversational pace is ideal for building endurance. Don't worry about speed — consistency matters more when starting out.
How do I calculate my pace per mile?
Divide your total time in minutes by the distance in miles. For example, if you ran 3.1 miles (5K) in 28 minutes, your pace is 28 ÷ 3.1 = 9:02 per mile. This calculator does it automatically for any distance.
What is a good 5K time?
Average 5K times vary by age and fitness. For beginners, under 35 minutes is a solid goal. Intermediate runners often target 20-25 minutes. Competitive runners aim for under 20 minutes. Elite runners finish in 13-15 minutes.
Should I run negative splits?
Negative splits (running the second half faster than the first) is a popular strategy because it prevents starting too fast and burning out. However, even splits (consistent pace throughout) are equally effective. Both are better than starting too fast.
How do I convert pace per mile to pace per kilometer?
Divide your pace per mile by 1.60934. For example, a 9:00/mile pace equals about 5:35/km. This calculator shows both automatically so you don't need to convert manually.
How does elevation affect my pace?
As a rough guide, add 15-20 seconds per mile for every 100 feet of elevation gain. Downhill sections are faster but not by the same amount. Hilly courses typically result in overall slower times than flat courses.
