One has built a track on the outskirts of his country's capital to aid his recovery from injury, the other trained in the US to fine-tune his Olympic hopes but one of them will be hoping to strike a psychological blow when they meet Saturday. Just how well Ethiopian Olympic champion Kenenisa Bekele and Oregon-trained British world gold medalist Mo Farah have progressed in their preparations will be gauged over 5,000 meters at this weekend's Prefontaine Classic Diamond League meeting. “Kenenisa is getting better by the week, so the race should be very competitive,” Bekele's manager Jos Hermens told Reuters. “He needs races to get in shape, so if it will be a good fast race, it will be a good effort for him.” The Ethiopian world record holder stormed to Olympic titles in both the 5,000m and 10,000m at the 2008 Beijing Games before a 2010 calf injury kept him off the track for more than a year. The Somalian-born Farah, meanwhile, has become the world's top ranked 5,000m runner and number two in the longer race. His double medal haul at the 2011 world championships included a silver in the 10,000m, making him a major British hope for the London Games. Both he and Bekele will pursue distance doubles at London, adding to the budding rivalry.
