FAQs.

How do I calculate my running pace?

Divide your total finishing time by the distance. For example, if you run a marathon (42.195 km) in 4 hours (14,400 seconds), your pace is 14,400 ÷ 42.195 = 341 seconds per km, which is 5:41/km. Our calculator above does this for you instantly.

What is a good pace for a beginner?

Most beginners start at 6:30-8:00 per km (10:30-12:50 per mile). A popular first target is running 5K in 30 minutes, which requires a pace of 6:00/km. Don't worry about pace early on. Focus on building the habit of running regularly.

What is the difference between pace and speed?

Pace is time per unit of distance (e.g. 5:30 per km), while speed is distance per unit of time (e.g. 10.9 km/h). Runners typically prefer pace because it's easier to track at each kilometre marker during a race.

How do I convert pace per km to pace per mile?

Multiply your per-km pace by 1.60934. For example, 5:00/km × 1.60934 ≈ 8:03/mi. Our calculator shows both km and mile paces automatically.

What are the half marathon splits for each goal time?

For even splits, run the same pace every km. For an even-paced 2-hour half marathon, run 5:41 per km: 28:26 at 5 km, 56:53 at 10 km, 1:25:19 at 15 km, 1:53:45 at 20 km and 2:00:00 at the 21.1 km finish. The table on this page lists the 5 km splits for each half marathon goal time from 1:15 to 2:30, and each row links to its pace page.

How do I work out my half marathon splits?

Divide your goal time by 21.0975 km to get your pace per km. Multiply that pace by 5, 10, 15 and 20 for each 5 km split. The calculator at the top of this page does this for any goal time.
