Chepkoech believed anyone can run the 3,000 metre steeplechase in under eight minutes and 40 seconds.
"I want to win the world championships. Running fast is important, but winning the gold medal is more appealing," she said.
This season, alongside setting the world record, Chepkoech banked the lucrative cheque for winning the Africa Championships and the Diamond League Trophy in the water and hurdles event.
"It is good to speculate on my next target. Maybe my next target could be to run under 8:40," said Chepkoech.
Currently, Chepkoech will take a deserved leave to rest his body and hope to return in December with early preparation ahead of the cross country season in February.
