Understanding Your Pace
Pace is measured in minutes per kilometre (or per mile). A lower number means a faster pace. Most runners find it easier to maintain a target pace than a target speed.
Speed is the inverse of pace, measured in km/h or mph. This is useful when setting a treadmill or comparing with cycling speeds.
Split times show how long it would take to complete common race distances at your current pace. These assume even pacing throughout the race.
Negative splits (running the second half faster than the first) is generally considered the best race strategy. Try entering a pace 10-15 seconds per km slower for your first-half target.
Frequently Asked Questions
What is a good running pace for beginners?
A good starting pace for beginners is around 7:00 to 8:00 minutes per kilometre (11:00 to 13:00 per mile). The key is to run at a pace where you can hold a conversation comfortably. As your fitness improves, your pace will naturally get faster.
How do I convert pace from minutes per kilometre to minutes per mile?
To convert from min/km to min/mile, multiply by 1.60934. For example, a pace of 5:00/km equals roughly 8:03/mile. This calculator shows both units automatically so you never need to convert manually.
What pace do I need for a sub-4-hour marathon?
To finish a marathon in under 4 hours, you need an average pace of approximately 5:41 per kilometre (9:09 per mile). This is a popular goal for recreational runners and requires consistent training over several months.
How are split times calculated?
Split times are calculated by multiplying your pace (time per kilometre) by the race distance in kilometres. For example, if your pace is 6:00/km, your 5 km split would be 30:00 and your 10 km split would be 1:00:00. This assumes an even pacing strategy.
What is the difference between pace and speed?
Pace is the time it takes to cover a unit of distance (e.g. 5:30 per km), while speed is the distance covered per unit of time (e.g. 10.9 km/h). Runners typically use pace because it is easier to maintain a consistent effort, whilst speed is more common in cycling and driving.
Should I run at the same pace for every distance?
No. Shorter races like a 5K are run at a faster pace than longer races like a marathon. A general rule is that your marathon pace will be 45-90 seconds per kilometre slower than your 5K pace. Training plans typically include a mix of easy runs, tempo runs, and interval sessions at different paces.
