Multivariate regression of multiple predictors on race speed. Multivariate regression results of the following predictors: event distance (log-transformed), event type (swim and run) competitors (men and women), and an interaction of competitor and event type on race speed (log-transformed). F-statistic: 9510 on 4 and 320 d.f. p-value: less than 2.2 × 10⁻¹⁶. Adjusted R² = 0.99. For each predictor, significant p-values in italics.
