Projected finish time

—

Empirical power-law projection; exponent 1.06 is only a starting assumption. Fitness, terrain, weather and distance affect accuracy.

Health inputs stay in this tab. Link sharing is disabled.

Formula

Use T₂ = T₁(D₂/D₁)^e. T₁ is known finish time, D₁ is known distance, D₂ is target distance in the same unit, and e is the editable endurance exponent. Projected time T₂ uses the original time unit.

Scope and limitations

Empirical power-law projection; exponent 1.06 is only a starting assumption. Fitness, terrain, weather and distance affect accuracy.

Inputs are checked for missing values and allowed ranges. A result outside the finite numeric range is not displayed. Rounding affects display, while the calculation uses the model’s numeric precision.

Check your units and assumptions before relying on a result. Changing a label does not convert a currency or physical unit.
