DMR Split Calculator

Enter the team goal and the calculator distributes it across the 1200m, 400m, 800m, and 1600m legs at equal effort using the Riegel exponent (1.06). A 10:00.0 goal becomes about 3:00.8 for the 1200, 56.4 for the 400, 1:57.6 for the 800, and 4:05.2 for the 1600, with exchange checkpoints at 3:00.8, 3:57.2, and 5:54.8.

Because the legs are different distances run by different athletes. Even pace per 400 would ask the 400m leg to run miler pace and the 1600m leg to hold 400 pace. Weighting each leg by distance^1.06 targets every leg at roughly the same relative effort, which is how coaches actually assign DMR legs. Treat the defaults as a starting point and adjust for your personnel.

The NCAA publishes multiplicative DMR factors between track sizes: for men, flat 200m to banked/oversized is x0.9866 and banked to flat is x1.0136; for women, x0.9894 and x1.0107. Undersized to flat is x0.9931 for men and x0.9959 for women. This calculator applies the flat/banked factors to your goal, and the full NCAA indoor track size converter covers every event and direction.

The standard distance medley relay order is 1200m, 400m, 800m, then 1600m anchor — 4000m in total. The 1200 leadoff starts from a standing start; the effect on a roughly three-minute leg is small, so the model does not add a separate leadoff adjustment.

Yes. Switch to the leg-splits mode and enter each athlete's split — 3:05.0, 58.0, 2:00.5, and 4:20.1 adds up to 10:23.6 — to project lineups from practice times or open marks.
