The national cross-country champion was controversially de-selected from her country's Olympic Games team despite running brilliantly throughout the year, particularly in Japan and the United States.

Momanyi also showed her world-class pedigree in May when she was edged out on the finishing line by Elvan Abeylegesse over 10km in Bangalore.

The American duo of Amy Rudolph and Sarah Slattery will be provide tough opposition for Momanyi, who also finished 10th at the IAAF World Cross Country Championships in March.

Rudolph is making a quick return to UK soil after finishing runner-up in the BUPA Great Wales Run at the end of July while Slattery is the reigning Pan-American Games 10,000m champion.

Guenther Weidlinger, just one of three Austrian athletes chosen to compete at the Olympics, will be aiming to match the victory he scored at the BUPA Great Manchester Run, also over 10km, in May.

Sweden's world-class 3,000metres steeplechaser Mustafa Mohammed is also among a strong overseas contingent along with top Spaniards Jose Manuel Martinez and Juan Carlos de la Ossa.

Mohammed warmed up well for the race by finishing seventh in the steeplechase at last night's Memorial Van Damme meeting in Brussels.

Former British number one distance runner Jon Brown, now competing for Canada, will also be looking for a fast run at his former Sheffield base.

Nick McCormick, an experienced British 1,500m and 5,000m star, steps up in distance and will be joined by fellow internationals Andy Lemoncello and Chris Thompson.
