What it means
About this calculator.
Pace versus splits
Average pace and splits diverge if you don't run even. Real-world races usually slow in the back half — for a marathon, plan to negative-split by 10–30 seconds/mile to land on your target.
FAQ
Questions people usually have.
Can I work backwards from a goal pace?
Not yet in this version. For now, enter the distance and your target finish time to see if the pace is realistic.
Is this elevation-adjusted?
No. On significant climbs, expect 12–15 seconds/mile slower per 100 feet of net gain.
