The following year she won the Kenyan junior cross title and assumed the lead in the global event at the 2007 IAAF World Cross Country Championships in Mombasa. However, an error with the final lap bell meant Korikwiang mistakenly treated the second to last lap as the ultimate one. Her premature efforts destroyed her chance at the title as she let others pass in the belief the race had ended and, after realising her mistake, she eventually dropped out having fainted mid-race in Mombasa's torrid conditions. In her final international junior competition she won the 5000 m bronze medal at the 2007 African Junior Athletics Championships.
