Tuhia he haere tonu mo tenei waahanga - I whiwhi ia i tetahi waahi ki te kapa motu o Kenya i muri i tana mutunga hei kaihauturu i te Kenyan Cross Country Championships i Nairobi i te Hui-tanguru. I te 2011 IAAF World Cross Country Championships
I kii ia i te tuawha o nga waahi ka awhina i nga taane o Kenya (tae atu ki nga toa toa iti a Paul Tanui me Vincent Chepkok) ki te mētara koura a te roopu. I muri tata mai ka rere ia i te hawhe marathon i te 60:03 meneti pai ki te wikitoria i te whakataetae Stramilano. Ko ia te tuatoru i te Giro di Castelbuono 10K i te Hurae. I oma ia i te tuawha o nga wa tere rawa atu mo te tawhiti i te hawhe marathon o Philadelphia i te marama o Hepetema, i oti te tawhiti i roto i te 58:46 meneti ki te patu i te rekoata katoa a Haile Gebrselassie o te United States. I timata a Kisorio i tana marathon i te 2011 New York City Marathon i te marama o Noema, a, he pai tana mahi tuatahi, i mutu i te tekau o nga haora 2:10:58.
