ATHX vs MacTuff: distancia, estaciones, precio y dificultad comparados (2026-27)

ATHX is a UK-born hybrid fitness competition, co-founded by coach Ollie Marchon, that now runs events across the UK, Europe and the United States. Each ATHX event is a continuous 2.5-hour session across six zones. Every competitor completes the same three workouts: a Strength zone (20 minutes), an Endurance zone (30 minutes) and a MetCon X zone (30 minutes). These are separated by a warm-up zone, a refuel zone and a recovery zone. The workouts and movement standards are published for each season.

Athletes enter as singles or pairs, in an ATHX or a harder ATHX PRO category, and pairs can be same-sex or mixed. Season results lead to the ATHX Finals, held in Lisbon in 2026. The fixed rest periods and clear divisions make ATHX accessible to first-timers, while the strength element suits athletes who lift as well as run and row.

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.
