The Kenyan passed away in hospital, where he'd been receiving treatment for an illness

Kipyegon Bett, the former world under-20 800m champion, has sadly passed away at the age of 26.

The Kenyan, who also secured a bronze medal over two laps at the 2017 World Championships in London, was receiving treatment for an illness in hospital.

According to Nation, Bett was vomiting blood due to damage to some of his internal organs.

Purity Kirui, who is Bett's sister and the 2014 Commonwealth 3000m steeplechase champion, told the outlet: "He'd been unwell for about a month and had been treated at AIC Litein Hospital as an outpatient. On Saturday (October 5), his condition deteriorated and was referred to Tenwek Hospital for further tests."

Bett started competing internationally in 2015 and claimed respective gold and silver 800m medals at that year's African and World Youth Championships.

The following season he became world under-20 800m champion in Bydgoszcz, clocking 1:44.95 to take the crown.

It was therefore no surprise to see Bett make a global senior podium in 2017.

In a pulsating race at the World Championships, Bett clocked 1:45.21 and placed third behind France's Pierre-Ambroise Bosse and Poland's Adam Kszczot.

That year he also won the 800m at the Shanghai Diamond League, running 1:44.70 to win the event in China.

However, Bett tested positive for EPO in 2018 and subsequently received a four-year ban.

He only ever raced once after it ended and that was in the 400m hurdles two years ago.
