How to use the running pace calculator
Select your pace in min/km or min/mile using the dials above — your projected finish times for every common race distance from 400 m to 100 miles update instantly. Switch to Goal → Required Pace mode to work backwards from a target finish time.
Min/km vs min/mile — what's the difference?
Min/km (minutes per kilometre) is the standard in most of the world, while min/mile is common in the US and UK. 1 mile = 1.609 km, so a 5:00 min/km pace equals roughly 8:03 min/mile. This calculator converts between the two automatically.
Race time calculator for every distance
Whether you are training for a 5K, 10K, half marathon, marathon, or ultra marathon, this free race time calculator shows your estimated finish time at the pace you choose. Use it to set realistic goals, plan race-day pacing strategy, and track your progress as you train.
Frequently Asked Questions
What is a good running pace?
A good pace for beginners is around 7–8 min/km (11–13 min/mile). Intermediate runners typically run 5–6 min/km (8–10 min/mile), while advanced runners sustain 4 min/km (6:26 min/mile) or faster.
How do I convert min/km to min/mile?
Multiply your seconds-per-km by 1.60934. For example, 5:00 min/km = 300 s × 1.60934 = 482.8 s = 8:03 min/mile. This calculator converts between the two automatically.
What pace do I need to run a sub-4 hour marathon?
To finish a marathon in under 4 hours you need to average faster than 5:41 min/km (9:09 min/mile). Set the pace selector to 5:40 min/km to see your projected finish time.
How far is a marathon in km?
A marathon is 42.195 km (26.22 miles). A half marathon is 21.0975 km (13.11 miles).
What does min/km mean?
Min/km stands for minutes per kilometre — the time it takes to run one kilometre. A lower number means a faster pace. For example, 4:00 min/km means you cover each kilometre in exactly 4 minutes.
What is a good 5K time for a beginner?
A good 5K time for a beginner runner is 30–40 minutes (6:00–8:00 min/km or 9:40–12:52 min/mile). With regular training most people can break 30 minutes within a few months.
How do I calculate my race pace from a finish time?
Divide your total time in seconds by the race distance in kilometres (or miles). For example, a 4:00:00 marathon = 14,400 s ÷ 42.195 km = 341.3 s/km ≈ 5:41 min/km. Use the Goal → Required Pace mode on this calculator for instant results.
What are running pace zones?
Pace zones divide your effort into bands — typically easy, aerobic, tempo, threshold, and interval. Training in the right zone improves endurance and speed. This calculator shows your zone based on the pace you select.
