How do I fix inaccurate treadmill speed readings?

Compare the displayed pace with 400m lap splits. If the gap is large, run the service calibration or schedule maintenance to realign belt speed.

What is the best way to use the interval presets?

Use the 5K, 10K, and marathon presets as a template for warm-up, work, and cool-down blocks, then adjust interval pace and rest duration to match your goal.

Why do indoor treadmill runs feel harder and how can I manage fatigue?

Indoor heat build-up elevates heart rate. Improve airflow with a fan, hydrate every 10 minutes, and monitor Zone 2 HR limits to keep effort sustainable.

Indoor Pace Converter

Convert treadmill speed, capture lap splits, and script interval sessions without leaving the console.

The converter syncs km/h and mph with min/km and min/mile, generates 400m lap splits, and offers ready-made interval presets so you can focus on running instead of math.

Core Terms

km/h · mph: Kilometers per hour or miles per hour. These are the units of speed typically displayed on a treadmill screen.
Pace: The time it takes to run 1 kilometer or 1 mile, measured in minutes and seconds. It's a key metric for a runner's speed.
Incline: The gradient of the treadmill. Setting it to 1% can simulate the effect of wind resistance encountered in outdoor running.
