HYROX, the ‘World Series of Fitness Racing,’ is set to stage its largest event ever at London ExCeL from December 4–7, 2025, with over 40,000 athletes expected to compete.
This landmark event underscores the rapid global expansion of the sport, which has seen a dramatic 5,614% surge in UK participation since its debut at London ExCeL in 2021. The first UK race in Birmingham in 2017 drew only 700 competitors.Event Highlights at London ExCeL 2025

According to HYROX, fitness racing is the dominant discipline for gym-goers, with over 52% naming it their primary sport. The organisation’s global footprint includes over 11,000 affiliated gyms internationally, with the UK community now boasting 1,700 affiliated gyms.
Moritz Fürste, Co-Founder and Chief Marketing Officer at HYROX, stated, “HYROX London is a landmark moment for us. I remember our first UK event here in London in 2021, and to see what HYROX has become today is truly incredible. The UK community has been a driving force for our growth, and this year’s expansion is another step toward realising our long-term vision.”
Fürste added that with HYROX now recognised as the newest discipline under the World Triathlon federation, the ambition for the sport to one day stand on the Olympic stage feels “more tangible than ever.”Looking Ahead: London Week of Fitness in 2026

HYROX Youngstars
The HYROX Youngstars two-day event (March 28–29, 2026) is specifically designed for children and teens. It mirrors the main race structure but adapts the distances, loads, and movement standards for a younger age group.
Jessica Petty, Global HYROX Youngstars Manager, commented, “With HYROX Youngstars, we’ve taken everything people love about HYROX – the atmosphere, the structure, the sense of achievement – and reimagined it for children… Bringing the race into the Week of Fitness in London, especially in the same venue where we first activated in 2024, feels like a full-circle moment.” Throughout 2026, Youngstars events will roll out at selected HYROX events across Europe, with US cities joining the calendar later in the year.HYROX Coaches Summit
The HYROX Coaches Summit will take place at Twickenham’s Allianz Stadium from March 27–28, 2026.

- A guaranteed HYROX London race entry for all attendees.
