Pace Calculator
Calculate pace per kilometre or mile from distance and total time.
Runners, cyclists, and swimmers use pace calculations to plan training sessions, set race goals, and track improvement. This calculator converts between pace (minutes per unit distance), speed, and finish times — helping you find the exact pace needed to hit your target time at any distance.

How to Calculate Your Running Pace
- Enter the distance — how far you ran or plan to run (e.g., 5 km, 10 km, 42.195 km for a marathon).
- Enter the time — your finish time or target time in hours and minutes.
- Click Calculate — the tool computes your pace per kilometre (or mile), speed in km/h, and projected split times.
- Plan your race — use the pace to set realistic goals and create negative-split or even-split strategies.
Frequently Asked Questions
What is running pace? ▼
Pace is the time it takes to cover a unit of distance, usually expressed as minutes per kilometre (min/km) or minutes per mile (min/mi). A 5:00 min/km pace means you run each kilometre in 5 minutes — equivalent to 12 km/h or about 7.5 mph.
What is a good running pace for beginners? ▼
Beginner joggers typically run at 7:00–9:00 min/km (11:00–14:30 min/mi). An intermediate runner doing 5K might aim for 5:30–6:30 min/km. Competitive runners target sub-4:00 min/km for 5K races. The most important thing is consistency, not speed.
How do I calculate pace from distance and time? ▼
Divide total time by distance. If you ran 10 km in 55 minutes: 55 ÷ 10 = 5:30 min/km pace. For miles, divide by miles instead. To convert min/km to min/mi, multiply by 1.609.
What are split times and why do they matter? ▼
Splits are the time for each segment of a run (usually per km or mile). Tracking splits helps you maintain even pacing and avoid starting too fast. A "negative split" (running the second half faster than the first) is the most efficient race strategy for most distances.
What pace do I need for a sub-4-hour marathon? ▼
A marathon is 42.195 km. For a sub-4-hour finish, you need an average pace of 5:41 min/km (9:09 min/mi) or faster. This is a popular goal that requires consistent training at around 5:20–5:30 min/km pace for long runs.
