2026 MUT Grand Prix schedule
Updated 12/26/2025
New in 2024: while all races will continue to be scored and counted as part of an overall MUT Series, we will also score separately a sub series with 4 sub-ultra trail races. And 6 sub-ultra trail races in 2025.
New in 2026: this year, we are going with two distinct series. One with 6 sub-ultra trails, aka SHORT series, the other with 9 ultras, aka LONG series. Sub-ultra races will NOT count toward the LONG series. SHORT will account for all scores. LONG will keep the best 7 scores. Also new in 2026, we’ll have 2 team scorings: one for SHORT and one for LONG.
