How it's calculated
Even pacing divides your target time equally across the distance: each split is the total time divided by the number of kilometres (or miles), and the cumulative column adds them up. Even or slightly negative splits — running the second half as fast or faster than the first — is the most reliable way to hit a goal time without fading.
