Running Distance Calculator | Pace, Time, Terrain Accuracy

Running Distance Calculator computes total distance from pace and duration with consistent unit handling. Terrain adjustment, energy expenditure, cadence, recovery load, and training context metrics are derived using deterministic formulas to support run planning, analysis, and performance tracking.
