Work split targets backwards from a goal time
Enter the two-mile time you are aiming at and the tool lays out half-mile split targets under three pacing strategies. Even runs all four half-miles at the same pace. A negative split starts slower than average and finishes faster than average. A positive split does the reverse. The size of the front-to-back spread is yours to set, anywhere from 0 to 10 percent.
The four segment multipliers always add up to four, so whichever strategy you pick the splits add back to exactly the goal time you typed. The one-mile cumulative split is shown in the same table, and the average 400 m lap treats two miles as 3,218.688 m, or 8.05 laps. Split times are rounded to whole seconds before being broken into minutes and seconds, so 59 seconds rolls into the next minute rather than printing as 60.
The tool does not say which strategy runs faster, because no governing body publishes an optimal split pattern for two miles. It also stores no point table and no pass mark, since published per-event scoring tables disagree between sources. It starts from a goal, so it is not meant for analysing a run you have already finished.
Frequently asked questions
The tool does not say. No governing body publishes an optimal two-mile split pattern, so the three options are laid out side by side.
Yes. The four segment multipliers always sum to four, so any spread value still totals exactly the goal time you entered.
That is a different job. This tool works forward from a goal time and does not break down a completed run.
