Hyrox is a fitness craze that shows no signs of dying out - with 1.3m people expected to compete in an event somewhere in the world this year.
The competition, which is split between running and fitness exercises, has proven particularly popular with young millennials and Generation Z - people in their twenties to early forties.
Its rapidly growing popularity has been attributed to social media.
Fashionable looks are often a non-negotiable for competitors, with many choosing to compete in high-end fitness brands, matching their outfits with their team members.
Allana Falconer, who works in sustainability and started competing in 2023, says she has "fallen in love" with it.
