Bett's first international championship was at the
2013 IAAF World Youth Championships, where at just 16 years old he set the Kenyan record in the rarely run
2013 World Youth Championships in Athletics – Boys' 2000 metres steeplechase. Bett also ran faster than the previous
world under-18 best, but was beaten by
Meresa Kahsay of Ethiopia. Starting in 2015, Bett was regular on the
Diamond League steeplechase circuit, cementing top-10 finishes in the
Shanghai,
Rome,
Stockholm,
Birmingham, and
Brussels meetings. Most notably, Bett finished 2nd in the 2016
Athletissima Lausanne as a 19-year old. After reigning Diamond League champion
Jairus Birech faded from the quick early pace, Bett led the race coming into the final water jump, but
Abraham Kibiwott passed him before the final barrier for the win. ==Statistics==
