Britain’s Mohammed “Mo” Farah smashed the European record in winning the 10,000m at the Prefontaine Classic Diamond League meeting on Friday with a time of 26min 46.57sec. Farah, who is enjoying a strong season after moving to Portland, Oregon, to train with former distance great Alberto Salazar, sliced more than five seconds off the previous European record of 26:52.30, set by Belgian Mohammed Mourhit in 1999.
