Ku sii qor faqradan - Inkastoo xaqiiqda ah in Goumri uu ahaa 21-aad 2007 IAAF World Cross Country Championships
, waxqabadka guud ee kooxda oo xoog leh (oo ay ku jiraan Anis Selmouni iyo Ahmed Baday) ayaa u keenay billaddii ugu horreysay ee kooxda ee dahabka ah ee dhacdada. Goumri wuxuu si guul leh ugu soo laabtay marathon-ka (markiisii ugu horreysay tan iyo 1997) 2007 London Marathon, isagoo kaalinta labaad galay 2:07:44, oo kaliya seddex ilbiriqsi ka dambeeya Martin Lel. Wuxuu ku tartamay takhasuskiisa cusub 2007 World Championships ee ciyaaraha fudud, laakiin ma uusan ku guuleysan inuu dhammeeyo tartanka. Goumri wuxuu isku dayay inuu wax ka bedelo waxqabadkaas isagoo iska diiwaan galiyay New York City Marathon. Sidii London, tartanku wuxuu ku soo dhammaaday dagaal u dhexeeya Lel iyo Moroccan, taariikhda ayaa ku soo noqnoqotay markii Kenyanku uu hore u socday si uu u guuleysto halka Goumri uu ku qancay kaalinta labaad (waqtiga diiwaangelinta 2:09:16).
