Methodology & sources

Split data: official per-runner checkpoint times for the 2025 Rzeznik 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; no figure on this page is modeled or extrapolated.
