2026 series format: The Grand Prix has two distinct series: six sub-ultra trail races in the Short series and nine ultras in the Long series. Short-series races do not count toward the Long series. The Long series uses the best seven scores, with team scoring tracked separately for each series.
Some registration links may not be available or up to date yet. We will update the schedule as information becomes available.
