ATHX Finals 2026 is a continuous 2.5-hour fitness competition held from November 27 to 29, 2026, at The Lisbon Exhibition and Congress Centre in Portugal. The event features individual and pairs categories with female, male, and mixed pairings.

The competition tests all aspects of fitness across six zones: Warm-Up, Strength, Refuel, Endurance, Recovery, and MetCon X. This event is designed to push participants to the next level of fitness through a set challenge in each zone.

Hero Challenge is an indoor fitness competition combining running with eight functional workout stations. The competition is completed exclusively in teams of two, with Men’s, Women’s and Mixed divisions.

Teams complete seven 800 m runs for a total of 5.6 km, alternating these running sections with eight functional workouts including BikeErg, SkiErg, sled work, carries, lunges and burpees.

Both athletes must run together throughout every running section, while the functional workouts are completed using a You Go, I Go format. Teams can decide how to divide the required repetitions or distance between the two athletes.
