Kiplimo won a selection trial for the World Mountain Running Championships in 2015 but was not allowed to compete due to his age. Kiplimo then moved to Italy and began competing in events. After winning a 2017 cross country event in Uganda, he moved back.
At the age of fifteen, Kiplimo won the 10,000 metres bronze medal at the 2016 IAAF World U20 Championships behind fellow East Africans Rodgers Kwemoi and Aron Kifle.
