MacTuff vs Nuts Challenge : distance, stations, prix et difficulté comparés (2026-27)

MacTuff is a Scottish events company, MacTuff Limited of Glenrothes, Fife, that runs mud and obstacle challenges for adults and children along with a road half marathon. Its obstacle events include the Really Muddy runs at Castle Fraser, Sauchen near Aberdeen, and in Fife and Kinross, plus MacTuff Kids events in Fife.

The Really Muddy events offer a 3 km kids course and 5 km and 10 km adult courses through mud, water and obstacles. MacTuff Kids is a roughly 3 km course where children run alongside participating adults, with obstacles built in two heights so that adults and children can tackle them together; the organiser sets adult-to-child ratios by age. Participants receive a T-shirt and medal, with free parking, spectator access, photos and bag drop. The events are aimed at families, groups, charity fundraisers and newcomers to obstacle running rather than competitive racers.
