Running pace calculator
Turn a finish time into a pace, or a pace into a finish time — for any distance — and get an even-split table for race day in miles or kilometers.
How to use it
- Know your goal time? Pick "I know my time," choose your distance, and see the pace you need to hold.
- Know your pace? Switch to "I know my pace" to project a finish time from a training pace.
- Race in miles or kilometers. Toggle the display units and the split table redraws for every marker on the course.
Why even splits work
The most reliable way to hit a goal time is to run it evenly — or slightly negative, meaning a touch faster in the back half. Going out too hard burns matches you can't get back, and most positive-split races end with a painful fade. The split table gives you a number to check at every mile or kilometer, so you can rein it in early instead of paying for it late.
From a target to a training plan
A goal pace is a decision; hitting it is a training problem. If you're not sure the pace is realistic yet, start with therace time predictor to ground it in a recent result.
Then let the work catch up to the goal.Trackside Training reads the sessions you sync from Garmin, Wahoo, Suunto, and Apple Health and adjusts your paces every two weeks as your fitness changes — no static spreadsheet required.
Frequently asked questions
How do I calculate running pace?
Pace is your time divided by distance. For a 5-kilometer run in 25 minutes, that's 25 ÷ 5 = 5:00 per kilometer. This calculator does it in both miles and kilometers, and can also work backwards from a pace to a finish time.
What is goal-pace or even-split running?
An even split means running each mile or kilometer at the same pace so your finish time lands exactly where you planned. The split table shows the elapsed time you should see at each marker if you hold steady — a simple race-day checklist.
How do I convert between min/mile and min/km?
One mile is about 1.609 kilometers, so a per-mile pace is always a larger number than the equivalent per-kilometer pace. Toggle the units and the calculator converts your pace, finish time, and splits instantly.
What pace should I run for my race?
Start from a recent result. Use the race time predictor to estimate a realistic finish time for your distance, then bring that time here to see the exact pace and splits you'll need to hold.
