JONNY Brownlee endured a disappointing end to his bid to land a home World Triathlon title in Leeds as he pulled out ahead of the final run with a stomach problem, after Vicky Holland had secured victory in the women's race.

The Bingley Harrier was forced out of the men's race with illness as South Africa's Richard Murray claimed victory.

The 28-year-old former Bradford Grammar School pupil from Bramhope claimed silver behind his older brother Alistair at the Rio Olympics nearly two years ago but stopped, holding his stomach with seven kilometres remaining.

He was treated by medics after the race in another cruel blow. Last year he made the podium only twice in races and in April finished a hugely disappointing seventh at the Commonwealth Games, three places ahead of Alistair, when the brothers had been expected to be fighting it out for gold.

Murray won in Yorkshire by eight seconds ahead of Spain's Mario Mola and France's Vincent Luis.

Olympic champion Alistair Brownlee was not able to take part in the Leeds event as he continues to recover from injury.

Non Stanford, meanwhile, had competed alongside Jonny Brownlee to help Great Britain claim silver at the World Triathlon Mixed Relay silver in Nottingham on Thursday.

However, the Welsh triathlete, who is based in Leeds, was not able to feature today, having fallen ill overnight.

Stanford said on her personal Twitter account she was "currently in hospital awaiting tests", but added: "Nothing serious I hope & sure to see you all soon."

Earlier today, Holland, who won the Olympic bronze medal, had won the women's race ahead of fellow British triathlete Georgia Taylor-Brown.

Holland finished with a time of one hour, 56mins and 32secs, which was some 17 seconds clear of her team-mate.

World series leader Katie Zaferes of the United States finished third.

"I can't believe I won that race – it was so brutal," Holland, 32, said.

"I was so tired on that swim as I tried to hang on to Jess (Learmonth), and on the bike I felt like I just had to hang on in there.

"It took me a full lap on the run to find my legs. All credit to the other British girls – they were so strong."
