Athletics & Running
Every athletics & running calculator on CalcEngines — unit converters, derived indices and interpretive tools, each with its formula, a worked example and the reference intervals it is judged against.
8 calculators in this section
- Age-Graded Performance CalculatorThe age-factored performance World Masters Athletics defines: your time times the published age factor, rounded the way the rulebook rounds it. The factor comes from you, because it is a published table and an approximation would be worst at the ages that use it most.
- Combined Events Scoring CalculatorDecathlon and heptathlon points from the published closed form, not an interpolated table: A × (B − T)^C for a track event, A × (P − B)^C for a field event, truncated. All seventeen coefficient sets, checked against six score sheets the IAAF printed in the same document.
- Pace Unit ConverterPace in one unit turned into pace in every other: seconds and minutes per kilometre, per mile, per lap and per 100 m. Pace only — pace and speed are reciprocals and cannot share one ladder of factors, and this page says why.
- Race Split Times CalculatorA target pace turned into a finishing time, a per-kilometre split and a pair of halves — even, or negatively split by a percentage you choose. Times are in seconds with the hours, minutes and seconds beneath, because the calculator cannot print a colon.
- Race Time Predictor CalculatorRiegel's endurance equation: a result at one distance turned into a predicted time at another, with the exponent as an input because it is a fitted number and not a constant. A marathon from a 5 km is where it is weakest, and this page shows by how much.
- Running Pace CalculatorPace per kilometre and per mile from a distance and a finishing time, with the speed beside it. The headline is in seconds, because the calculator has no text type and cannot print a colon — the whole minutes and the remaining seconds are the two figures under it.
- Track Lane Distance and Stagger CalculatorThe exact length of one lap in any lane, and the stagger that makes a one-lap race fair, from the kerb radius, the lane width and the straight. It reproduces World Athletics' own 400 m marking plan to the millimetre.
- Wind Reading and Altitude Legality InterpreterWhether a wind reading leaves a performance eligible for a record, under World Athletics Competition Rule 31 — and what the rule does not do. It does not correct the time, there is no altitude limit at all, and a raw +2.03 is recorded as +2.1, which makes it illegal.
