​Olympic 5,000 metres champion Vivian Cheruiyot has said she wants to retire at 40 to take up coaching and mentoring of young athletes. 

In her meticulously-planned career, the 33-year-old policewoman, who was recently crowned the 2016 Sports Personality of the Year, also said she would like to have a second baby in 2020.

Speaking at a 2017 IAAF World Under-18 Championships media workshop in Eldoret town, Cheruiyot emphasised the need for good planning for athletes. 

“We won’t run the entire of lives since at some point we age so it is important for young athletes to plan early their lives so that they sustain themselves after retirement,” said Cheruiyot.
