Pace vs Speed
Pace is the time it takes to cover a unit of distance (e.g., minutes per kilometre), while speed is the distance covered per unit of time (e.g., kilometres per hour). Runners typically use pace, while cyclists prefer speed.
Total Seconds = Hours × 3600 + Minutes × 60 + Seconds
Pace (sec/unit) = Total Seconds ÷ Distance
Speed = Distance ÷ (Total Seconds ÷ 3600)
1 mile = 1.60934 km
Common Race Distances
5K: 5 kilometres – a popular beginner-friendly distance. 10K: 10 kilometres – a common intermediate race. Half Marathon: 21.0975 km (13.1 miles). Marathon: 42.195 km (26.2 miles).
Improving Your Pace
To improve your running pace, incorporate interval training, tempo runs, and long slow distance runs into your routine. Consistency and gradual progression are key. Monitor your heart rate zones using our Heart Rate Zone Calculator to train at the right intensity.
Nutrition for Runners

Frequently Asked Questions
What is a good running pace?
For beginners, 7-8 min/km is typical. Intermediate runners: 5-6 min/km. Advanced: under 5 min/km. Elite marathoners run at about 3 min/km. Pace depends on distance, fitness, and conditions.
How do I calculate pace from time and distance?
Pace = Total Time ÷ Distance. For example, running 10 km in 50 minutes gives a pace of 5:00 min/km or speed of 12 km/h.
