Split data: official per-runner checkpoint times for the 2025 Rzeźnik Ultra, 128 finishers at 5 timed checkpoints. All split-derived figures describe finishers only. Runners who dropped or missed a cutoff do not appear in split data, so buffer statistics understate how tight cutoffs are for the full field. Medians are used throughout. Apart from the finish-time explorer, which scales the median finisher's splits to the time you pick, no figure on this page is modeled or extrapolated.
