Simple time estimation for running routes

Running Simulator

Calculate complete GPX running routes with realistic gradient rules, pace profiles, intermediate times, and breaks.

Flat Pace

The pace and speed entries are not available with your current access.

Optional for power users: adjust the gradient model, tactics, special sections, breaks, and other details.

Gradient model

Neutral is 0 ± 0.5 %. For all other bands, starting values are derived from flat pace.

The pace and speed entries are not available with your current access.

All pace values are editable. Format: m:ss per km.

Band Gradient Pace
Tactic

Many runners aim for a 50:50 or slight negative split.

Special Segments Optional

Define individual segments with your own pace. This is useful for known technical sections, a long climb with a well-known target pace, planned walking sections, or other parts of the route where the standard model is intentionally replaced. Logic: Start is inclusive, end is exclusive, meaning 16–19 km applies to segments 16–17, 17–18, and 18–19. For each design, average, min, and max incline of the route are calculated.

Optional: Define the segment, view the gradient, and set a fixed pace if needed.

Breaks Optional

Set optional break points with km and duration.

Optional: Define and save a break point with duration.
