Individually, she won medals at the African Cross Country Championships and the African Championships in Athletics (1500 m) in 2012.
She initially started out as a 1500 metres runner and came seventh in that event at the 2007 All-Africa Games. She was the winner of the 2008 Cross de Atapuerca and went on to finish in eighth place at the IAAF World Cross Country Championships that year. She won the 2009 Lotto Cross Cup de Hannut cross country race in 2009.[1]
Muriuki placed sixth at the 2010 IAAF World Cross Country Championships, which helped the Kenyan women to the world team title. She was the runner-up at the 2012 African Cross Country Championships behind teammate Joyce Chepkirui, both of whom shared the team title.[2] A week later she took third place at the Lisbon Half Marathon, finishing behind Diana Chepkemoi.[3] Showing her versatility, she went back down to the 1500 m at the 2012 African Championships in Athletics and won the bronze medal for Kenya in a personal best of 4:06.50 min.[4] She ran on the American road circuit in August and won both the Beach to Beacon 10K and the Falmouth Road Race.[5] She was runner-up at that year's Portugal Half Marathon (also held in Lisbon).
Muriuki secured the Kenyan national title in cross country at the start of 2013, guaranteeing selection for the 2013 IAAF World Cross Country Championships.[6]
