Whakaotihia te rerenga e whai ake nei: I whakapumautia a Chepkorir i a ia ano i roto i nga kaikawe haurua marathon o runga o te ao me tana wikitoria i te haurua marathon o Berlin i te Poutu-te-rangi 2010, e rere ana i te waa whaiaro 69:43 meneti ki te patu i a Eunice Kales. I hoki ia ki te taone nui o Tiamana mo te whakataetae BIG 25 Berlin, a ko ia te tuatoru. I kōwhiria ia ki te whakataetae mō Kenya i te
2010 IAAF World Half Marathon Championships engari na te wharanga i whakaiti tana wa i mua i tana tiimata ki te ao matua i reira.
