He won his fourth consecutive title at the Ugandan Cross Country Championships in February 2011, comfortably seeing off challenges from national rivals Stephen Kiprotich and Geofrey Kusuro. However, Kiprotich finished ahead of him at the 2011 IAAF World Cross Country Championships, where he was eleventh, and the Ugandans took the bronze team medal. His 2011 season was abruptly brought to a halt as he was diagnosed with malaria and typhoid. He missed the 2011 World Championships in Athletics as a result, but returned to defend his 5000 m title at the 2011 All-Africa Games and won for a second time running. He returned to grass competitions in 2012 with a third-place finish at the Cross de Itálica.
