Relay Split Calculator

Enter the team goal and the calculator assigns the leadoff leg a target 1.0 second slower than each flying leg, with legs 2–4 evenly sharing the remainder. For a 3:20.0 goal that is 50.75 for leg 1 and 49.75 for legs 2–4, with exchange checkpoints at 50.8, 1:40.5, and 2:30.3.

Leg 1 starts from blocks or a standing start, while legs 2–4 receive the baton moving and effectively run a flying start. This calculator models that with a simple fixed offset — the leadoff target is 0.5s slower than a flying leg in the 4x100, 0.8s in the 4x200, and 1.0s in the 4x400 and 4x800. It is a coaching convention for setting targets, not a physics model.

Yes — pick 4x100 and the same model applies with a 0.5s leadoff offset. Keep in mind 4x100 legs are baton-carry segments measured exchange to exchange, so treat the targets as zone-to-zone approximations; exchange quality moves real 4x100 splits more than any calculator can.

Yes. Switch to the leg-splits mode, enter each runner's split, and the calculator adds them into a team total — the classic 4x4 time calculator question when you are projecting a lineup from practice splits or open marks.

Not exactly. Flying legs (2–4) typically split faster than the same athlete's open time because they start at speed, while the leadoff usually splits close to open ability. That is exactly the asymmetry the leadoff offset builds into the targets.

The distance medley relay has unequal legs (1200-400-800-1600), so even leg targets do not apply — use the dedicated DMR split calculator, which weights each leg for equal effort and includes NCAA track-size conversion factors.
