What Running Split Calculator does

A running split calculator that determines the consistent pace needed to finish a race or training run in a target time. Users enter total distance, total time, or a specific pace, and the tool outputs the exact split times required for each interval. The interface supports multiple units and includes quick conversions (e.g., 4 km ≈ 2.49 miles), plus a brief explanation of what splits mean and how they apply to competition preparation. A "share result" button and links to related calculators (training pace, race predictor, VO2 max) are also provided.
