How this race pace calculator works
Pace is finish time divided by distance. Enter a race distance (or tap 5K, 10K, half marathon, marathon) and your goal or actual finish time to get minutes per mile or per kilometer. Flip the mode to solve for finish time from a target pace, or for distance from time and pace.
Useful race distances

FAQ
Is this the same as a generic pace calculator?
This tool is built for race distances and finish planning. The homepage targets race pace calculator use cases (presets, splits, mile/km). For treadmill incline, cycling speed, or Jeff Galloway–style run/walk, use the linked tools.
Do you store my numbers?
No. Calculations run entirely in your browser. See Privacy.
Miles or kilometers?
Use the Miles / Kilometers toggle. Pace and speed labels update automatically, and you can see the equivalent pace in the other unit.
