Hyrox Split Planner

You give a target finish time; the planner does not predict your finish. It looks at results in your division, gender and age band that finished near that target and takes the median of every run, every station and the roxzone. The typical range is the middle 50% of those results.

Those medians add up to a little less than the target, because the median of a sum is not the sum of the medians. They are scaled so the plan adds up to your target to the second. The typical ranges stay as observed and are never stretched. The plan is built from many results: no single athlete ran exactly these splits.

Change a split and the other unlocked splits make up the difference, each in proportion to the room it still has inside its typical range, so the finish stays the time you entered. Lock a split to keep it out of that. If there is not enough room, the change stops where it still works and the planner says so.

The time budget moves time between all runs and all stations at once: what the runs gain, the stations give back, shared by the room each split has left. The roxzone and locked splits stay where they are. The slider under the budget covers only the room that is actually available.

Your rank compares the target with all results in your division, gender and age band for the seasons shown. When an age band has too few results, the planner uses all ages in that division instead and says so above the plan.
