Could Hyrox's Olympic ambition spell the end for triathlon?

World Triathlon says the partnership is designed to "benefit the entire World Triathlon movement",, external with new opportunities to engage athletes and audiences, and a stronger platform to grow triathlon and multisport from grassroots to elite level.

The question for athletes is, how?

European champion Roksana Slupek, of Poland, said she was "not against the idea", but wanted more information.

"What's the benefit for us, for triathlon? It's nothing against Hyrox," said Slupek.

However, Stapley called the move an "attack on our whole existence" and is concerned that World Triathlon could direct attention and resources towards Hyrox's Olympic ambition - at the expense of his own sport.
