F45 Training, from FIT House of Brands has become the official global gym partner of fitness racing company, Hyrox.

The collaboration will span 12 premium Hyrox events across four continents in 2026, including the London event in April. The partnership will include co-branded training content, member activation programmes at F45 studios, and on-site programming at Hyrox events designed to introduce new athletes to both brands.

“We’re incredibly excited to welcome F45 Training as our affiliate gym partner,” said Douglas Gremmen, chief growth officer at Hyrox. “Together, we’re creating a pathway for millions of F45 Training members to experience the energy and challenge of Hyrox competition at the world’s most iconic event venues.”

Tom Dowd, chief executive officer of FIT House of Brands, says: “Hyrox represents the ultimate test of everything our members train for every day – functional strength, cardiovascular endurance, and the mental toughness to push through. Partnering with HYROX on a global scale is a powerful statement about where F45 is headed.”

As the title partner for the Americas Regional Championships in Washington DC earlier this month, F45 hosted a 5k community-focused run around the city, as well as operated the F45 Lounge – a dedicated space for competitors and supporters to recover.
