Cassandre Beaugrand strides to Supertri E world title in London
France’s Cassandre Beaugrand has today dominated the 2025 Supertri E World Triathlon Championship, leading from the starting pistol until the finale of the gruelling nine-discipline triathlon under the lights of London’s Aquatics Centre.
Unlike in the men’s event – a comeback classic won by Maxime Hueber-Moosbrugger – the 27-year-old Beaugrand never looked likely to give up her lead over Britain’s Beth Potter, steadily increasing her advantage to over thirty seconds by the end of the triple triathlon. Julia Broecker of Germany was third a distant 1:23mins behind.
“It was very brutal out there; I forgot just how hard this racing is,” said Beaugrand at the finale. It is very challenging racing Beth but it’s nice having a big battle like that. If I blew up then I blew up, but I just really happy with the result today.”
Beaugrand’s win was her second Supertri E victory in London after victory here in 2022, joining the Olympic triathlon title and World Triathlon Championship and many more in her ever-expanding trophy cabinet.
Potter’s second-place finish continued her remarkable record of never finishing lower than second in a Supertri E event, having won this event in London in 2023 and 2024 and the Supertri E World Championship in both 2022 and 2024.
“That was really hard today,” was Potter’s understated verdict on her latest battle with Beaugrand. “I dug as deep as I could and hold the gap as long as possible, but it’s onwards and upwards from here.”
RIVALRY RESUMED
The London Aquatics Centre in Queen Elizabeth Park was once again the host of the Supertri E World Triathlon Championships, with 10 triathletes qualifying from the morning heats, including heat winners Beaugrand and Potter resuming their rivalry after a series of classic encounters in 2024.
The World Championship race consisted of three stages over the Supertri E format (200m Swim – 4km Bike – 1km Run; 200m Swim – 4km Bike – 1km Run; 200m Swim – 4km Bike – 1km Run), all competed back-to-back with no break between the stages.
STAGE 1
Swim: 200m
The race’s first swim began with Olympic champ Cassandre Beaugrand in the ascendency, exiting the Aquatics Centre’s 50m pool with a narrow three second advantage over Zuzana Michalickova of Slovakia, with Beth Potter five seconds back in fifth.
Bike: 4km
Onto the E World Championship’s first bike leg and Potter narrowed the deficit slightly to Beaugrand, who seemed troubled by tech difficulties on the bike but still maintained a 4sec advantage. Beaugrand’s lead would extend to 6secs by the finale of the bike
Run: 1km
Onto the run leg on the curved treadmill and Beaugrand’s effortless stride saw the 27-year-old increase her advantage to 9secs over Potter, with the chasers over 20secs in arrears.
STAGE 2
Swim: 200m
The second swim began with Potter closing the gap to 7secs, with the field now logging nearly 30 seconds behind. Another classic Beaugrand and Potter battle looked on the cards, with the rest of the field surely now vying for bronze. Beaugrand would exit with an 8sec lead over Potter.
Bike: 4km
A slick transition by Potter saw her instantly narrow the gap to 6secs, but Beaugrand would maintain her lead and then increase it to 12secs despite Potter’s best out-of-the-saddle efforts.
Run: 1km
Beaugrand would hit the treadmill at 18.5km/h pace, despite sporting a calm and casual demeanour. That lead would be 14secs by the end of Stage 2 but, with the men’s race going to the wire, Potter still had hopes of a comeback.
STAGE 3
Swim: 200m
The final swim of the day commenced with Beaugrand again at the fore, her lead first 15secs and then 17secs, the biggest gap of the day.
Bike: 4km
Beaugrand’s lead looked insurmountable at the start of the bike leg, with Potter now 18secs behind and the rest of the field over a minute back. The gap to Potter would be 22secs with 1.5km to go, 24secs with 1km to go and 26secs at the finale.
Run: 1km
Beaugrand looked in complete control throughout all of the final 1km run leg, maintaining her 18km/h pace to build a lead of 30secs that Potter couldn’t answer. Julia Broecker of Germany had made the third spot her own 1:20mins back, but all eyes were on Beaugrand at the front as she took her second Supertri E World Championship.
