Cadence
Cadence Calculator
Use this to see how small changes in rhythm or stride length affect pace, 5K, 10K, half marathon, and marathon estimates.
- Combines cadence and stride length to estimate pace.
- Shows the result for common race distances.
- Use it to explore tradeoffs, not to force a single perfect cadence.
Cadence and stride length together create speed. This tool shows why a small rhythm change or a slightly longer stride can noticeably change pace and finish time.
- Cadence is steps per minute from your watch or cadence target.
- Stride length is the distance covered by one step; many watches estimate it, and beginners can start with a rough value.
- Choose a common race distance to see the projected finish time.
The result is a model, not a promise. A faster projection only helps if the cadence and stride length still feel relaxed, efficient, and sustainable.
- Change one variable at a time so you can see its effect.
- Try small cadence changes before making big form changes.
- Use a metronome for short easy segments when you want to practice a steadier rhythm.
After you find a realistic target, use short metronome segments to practice the rhythm before expecting it to hold for a full race.
How do cadence and stride length change my finish time?
Projected pace 5:53 min/km
Projected finish 29:25
Mechanical estimate only. Do not force a longer stride to chase a faster result; keep changes small and stop if landing, knees, calves, or Achilles feel worse.
