Peter Chumba (born 20 December 1968) is a Kenyan male former long-distance runner. He was the first athlete to achieve a gold medal double at the IAAF World Junior Championships in Athletics, taking victory in the 5000 metres and 10,000 metres.[1] This feat has since been matched by Haile Gebrselassie, Daniel Komen and Assefa Mezgebu.[2] While all three of those athletes won senior medals at global level, this feat would remain the highlight of Chumba's career.[3]
