Use this finish time calculator to estimate your race result from your target pace and distance. Choose miles or kilometers, enter your planned pace, and get your projected finish time along with a simple breakdown you can use to pace yourself consistently in training runs or on race day.
FAQs on finish time calculator
How do I use the Run Time Calculator to get a finish time?
Pick the Pace tab, enter your pace and distance, and the calculator will show your finish time. For example, 9:30 per mile for 10 miles comes out to 1:35:00. Use this when you want a simple time goal for a run or race.
Can it calculate my pace from a recent race result?
Yes. Pick the Pace tab, enter your distance and finish time, and you will get your pace per mile or per kilometer. Example: 5K in 28:00 is about 9:01 per mile (about 5:36 per km).
What time and pace format should I type?
Use hours:minutes:seconds for time, even if hours are zero (example: 0:35:00). Use minutes:seconds for pace (example: 8:45 per mile). If the result looks wrong, check that you did not swap minutes and seconds.
Miles vs kilometers: which should I choose?
Choose the unit that matches how you train and how your race is measured. Switching miles to kilometers changes the pace number, but the effort stays the same. A pace that looks “faster” in minutes per kilometer can still be the same speed.
Why don’t my splits show up, or why do they look off?
Splits show after you enter enough info to calculate a full result, usually distance plus time (or pace). If splits look uneven, check your distance unit and the split interval setting. Rounding can make the last split slightly different.
What are negative splits, and should I use the slider?
Negative splits mean you run the second half a bit faster than the first half. A small setting (like a few percent) can help you avoid starting too fast. If you are new to pacing, keep it simple and aim for steady splits first.
Why doesn’t the calculator match my GPS watch or treadmill?
Small gaps are normal because GPS can drift and treadmills can read differently than your actual pace. Courses can also run long on turns, tangents, and crowded starts. Use the calculator for planning, then adjust based on what you can hold on the day.
How do I turn the result into a workout this week?
Use the pace as a target for short repeats, then jog easy between them. Example: if your goal pace is 9:00 per mile, try four to six repeats of two to three minutes at that pace. Keep easy runs easy, then test the pace again in two to four weeks.
I completed my first 10K on a dare. In a year, I ran a half-marathon. Another year later, I finished a marathon race. Today I run 4 marathons a year and a half-marathon every week. I learned everything about running the hard way. So, I help runners achieve better results easier.
