World championships are held every year, with contestants taking part in singles and doubles races.
The 2024 world championships in France featured a new relay event by nationality.
The sport is closely related to CrossFit, but has different, simpler exercises and prioritises endurance over raw strength.
Its popularity is primarily put down to two things: accessibility and visibility.
Hyrox has been designed with the intention of going viral, whether by giving contestants patches instead of medals to wear on their gym bags, or by pushing “training club Tuesdays”, getting people to tag gyms that offer classes.
The top athletes in the sport are doing the event in under an hour.
But Hyrox competitor and former Wales rugby player Laura Payne said the race could be geared to all abilities, with some using lower weights, walking the sprints and taking up to three hours to finish.
“It’s quite open and inclusive,” said the co-owner of Penarth gym Arth Strength.
