Pace Calculator

Frequently asked questions

How does the Pace Calculator work?

Enter a distance and target pace for a run, swim, bike or a multisport race and it estimates your finish time and per-leg splits instantly in your browser — no sign-up, and nothing you type leaves your device.

Can I calculate a full triathlon time?

Yes. Choose Triathlon mode, then enter each leg's distance and pace plus optional transition times. Presets for Sprint, Olympic, Half (70.3) and Full distances fill in the distances for you.

Does it support metric and imperial units?

Yes. Toggle between metric and imperial and your entered values convert automatically — swim pace per 100 metres or 100 yards, bike speed in km/h or mph, and run pace per kilometre or mile.

Which sports and formats does it support?

Single sports — run, swim and bike — plus multisport formats: triathlon (swim, bike, run), duathlon (run, bike, run), aquathlon (swim, run) and aquabike (swim, bike). Each multisport mode adds the right legs and transition times, with distance presets for common race distances such as Sprint, Olympic and Half.

Is the Pace Calculator free?

Completely free. It runs entirely in your browser, with no account, no ads and no data collection.
