The supertri E World Championship started life as the ‘Super League Triathlon Arena Games’.

It sees athletes compete using both real-life and virtual racing (using MyWhoosh) within an arena environment. That means the swimming will take place in a pool, while the cycling and running will be on smart bikes and treadmills.

This format used to take place over a few locations, but now it’s a one-day World Championship event in partnership with World Triathlon.

For the first time, the 2025 event will mirror the unique and high-pressure Supertri format of three continuous rounds of swim, bike and run.

The racing begins with a number of qualifying heats, which will result with just 10 men and 10 women making it through to the finals in the evening.

The morning heats will see athletes complete two continuous rounds of swim-bike-run, and the finals will then take place over three stages of swim-bike-run.

A number of big names have been announced ahead of the London event, including Olympic bronze medallist Beth Potter, reigning Olympic and world champion Cassandra Beaugrand, three-time Olympic medallist Jonny Brownlee; 2023 world champion Dorian Coninx; and reigning Supertri E champion, Chase McQueen.

Also back for 2025 is Fanni Szalai, the Hungarian prodigy who famously made global headlines when she debuted as a 15-year-old in Sursee, Switzerland, two years ago, creating a massive shock by not only qualifying for the finals but finishing on the podium.
