ATHX vs TYRUN: distance, stations, price & difficulty compared (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.

TYRUN is a seasonal fitness race series in Belgium and the Netherlands, run by TYRUN B.V. Each season brings a new workout with new exercises, distances and standards, and races during the season count towards a leaderboard and a season final.

The Season 2 course is four laps, each a 600 m run followed by two stations, for 2.4 km of running and eight stations in total: Echo Bike, seated sled pull, weighted step-ups, med ball sit-ups, a 1,000 m row, devil's presses, a 1,000 m SkiErg and a sandbag carry over a yoke. Athletes race as singles or doubles in Scaled, Open or Pro divisions, which change only the loads and calories, or as four-person relay teams in Open. Most athletes finish in 60 to 90 minutes and there is no cut-off. Season 2 stops include Liège, Hasselt, Amsterdam (Vijfhuizen) and Antwerp, with the finals in Ghent. The Scaled division is aimed at first-time racers.
