Ethiopian Olympic 10,000 and 5,000 metres champion Kenenisa Bekele will head a field including his younger brother Tariku in the British Olympic trials 10,000 final in Birmingham this Friday.
Tariku Bekele, a former world indoor champion, his compatriot and former world cross country champion Gebre Gebremariam and Uganda's Commonwealth 10,000m and 5,000m gold medallist Moses Kipsiro will also run at the Alexander stadium.
Britain's world 5,000m champion and 10,000m metres silver medallist Mo Farah will not take part after opting to run the 1500m as part of his speed training. Farah beat Kenenisa Bekele over 5,000m in Eugene this month.
"This race will be a great opportunity for me to compete against some of the best distance athletes and secure my place in the Ethiopian Olympic team," Kenenisa Bekele said. "I am improving with every competition this season so I will be expecting to run a very fast race."
