In 2001, Kemboi won an Athletics Kenya steeplechase event in Kakamega. His performance caught the eye of coach Paul Ereng, who invited him to train at the High Altitude Training Centre in Eldoret. This marked the beginning of his professional journey.

Kemboi's dedication paid off when he was named the 2013 African Male Athlete of the Year by all-athletics.com. The same year, Athletics Kenya honoured him as the Male Athlete of the Year. In 2004, he received the Order of the Grand Warrior of Kenya.

Challenges and Setbacks
