Field pace: the median finisher's pace on the segment into this checkpoint, relative to their own whole-race average — right/orange = slower than race pace, left/blue = faster. PRE, FV and Mål are run-in mats spread across the last 500 m; their segments are too short for their pace figures to mean much. Runners who missed a cutoff or dropped are not in the data (finishers only).

Methodology & sources

Split data: official per-runner checkpoint times for 4 Lygnernslingan 85 km editions (2022–2025), 249 finishers at 9 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.
