It isn’t every day that an entirely new mass participation racing concept emerges that can take the world by storm. But, that’s exactly what’s happened over the past few years with the rise of HYROX, a new racing format, combining functional fitness and endurance in an indoor mass participation race.Launched in Germany in 2017 by veteran multisport race organizer Christian Toetzke with the help of co-founder Moritz Fuerste and a select team of colleagues, HYROX has exploded in popularity to become the fastest growing mass participation fitness concept in the world. So what is HYROX? What makes it so special? How does it relate to other race formats out there like obstacle racing? And, how does the highly lucrative business of HYROX work? Well, we’re going to be going through all that and more today with the help of my guest, HYROX USA & UK Managing Director, Douglas Gremmen.In this episode:Combining fitness and endurance in coming up with the HYROX concept/formatThe history of fitness racing before HYROXBringing mass participation racing to gym goers (and giving gym goers something to train for)Rolling out HYROX in Europe, the US and the rest of the worldObstacle races vs HYROX: differences and similaritiesHYROX in the Olympics?Designing a scalable race format: making workouts accessible, safe, easy to monitor and easy to transport between venuesRace timing in a HYROX race (it's complicated!)Getting thousands of people around an indoor racing courseHow large can a HYROX race get?What it costs to enter a HYROX event (and what you get for it)Involving spectators in the HYROX race experienceGrowing HYROX internationally through franchiseesHYROX' gym partnerships driving growth and secondary revenueA look at HYROX' growing competitionThanks to RunSignup for supporting quality content for race directors by sponsoring this episode.
