2025 Worlds — Test 1: Endurance
Accumulate max calories on the SkiErg in 20 minutes, with a shuttle-run buy-in every 2 minutes:
- 0:00 — 1 Shuttle Run, then ski
- Every 2 min the shuttle-run count increases by 1 (2, 3, 4 … up to 10 at 18:00)
Fail to finish the shuttle runs within a 2-minute window and you're eliminated. Score is total calories. Time cap: 20 minutes.
Athletes perform 1 shuttle run, then accumulate SkiErg calories until the 2:00 mark, when they stop to complete the next set of shuttle runs (increasing by one each round). The SkiErg does not reset, accumulating calories across all rounds. If an athlete cannot finish their shuttle runs within the window their test ends, scored by rounds completed with calories as the tiebreak.
Athletes may stop skiing early to prepare but must not cross the shuttle start line until the interval begins, and may not stay on the SkiErg past the 2:00 mark to bank extra meters. The damper may be adjusted but the monitor may not be touched. An athlete eliminated in an earlier round cannot finish ahead of one who reached a later round, regardless of calories.
Each movement links to its full rulebook entry — standards, rep requirements, and the judging reference technical officials train against.
