The 24-year-old Jeffcoat motored away from Austria’s Sara Vilic, Australia’s Kelly-Anne Perkins and Spain’s Miriam Casillas Garcia in the closing stages to grab gold in 59min 28sec on the 10th stop of the tour.

Vilic finished a second behind to take silver, while Perkins earned bronze on the same time.

“You really won’t wipe this smile off my face,” said Jeffcoat.

“To come away from Tiszy with the win just blows my mind.

“I’m pretty determined when you give me a challenge so when it came down to a sprint finish, I thought ‘go for it and don’t look back’.

“To take that tape is so surreal.

“It was one of my poorest swims and I was farther back than I would have liked, but I tried to stay calm.

“I first came here in 2016 and my whole family came and I’ve always loved it, so to top it off with a win is just great.”

The men’s race was no less dramatic, with Hemming charging through the final 100 metres to win gold on 53:43.

Ryan Fisher of Australia and South Africa’s Wian Sullwald finished second and third, respectively, both a second down on the victor.

“After a rough start to the season, this feels really good,” said Hemming.

“It’s really fun to be doing a sprint finish, but it’s even better with your buddies.”
