YVONNE Murray fought back tears of frustration and anger yesterday at the end of the Britannia Women's 10,000 metres in Glasgow.

Having been reduced to a walk by a severe stitch, the Commonwealth champion dropped from the lead to seventh as Australian Natalie Harvey, the World Student 10,000 metres track champion, confirmed the arrival of a new inter-national talent. The 23-year-old from Melbourne set a course record of 32min 38sec, collecting #950 and claiming the scalps of two notable Kenyans who took the minor medals.

There could be further tears from Murray today, with every indication pointing to the end of her reign as Commonwealth champion. ''I promised to give a decision by Monday to the team management, on whether I'll compete in Kuala Lumpur,'' she confessed. Pressed by journalists on her prospects for Malaysia, and her future, she demurred politely: ''Ask me tomorrow.''

A year ago, Motherwell's Murray finished this event fifth, racked by cramp; she was stretchered off on Tyneside with food poisoning; and recovering from injury, was blown away at Balmoral. It would be simplistic to portray her recent career as a series of disasters, for within the past 12 months she has also broken records held by Olympic silver medallist Elana Meyer and London marathon winner Joyce Chepchumba. Clearly, she still has much to offer, and obituaries are premature, but I believe Murray is ready to turn her back on track championships.

Yet for long periods yesterday she seemed set to redeem her fortunes. ''It's the first time I've felt like my old self, and in control,'' said Murray, ''but then I stitched, and the more I tried to relax, the tighter my stomach became.''

There is a world of difference between spring in Scotland, and the heat and humidity of a Malaysian summer, where Harvey aims to do the 5000m, but the race was also demoralising for Lynne MacDougall, who also hopes to run that distance in KL. Recently ill, she raced prematurely, finishing one place behind Murray in the record field of 4322.

MacDougall, a 1984 Olympic 1500m finalist, went with the early pace in a group of eight. Last year's runner-up, Teressa Duffy, was first to succumb, as Harvey injected a surge on a steady climb towards 3000m. MacDougall followed soon after, but Murray looked relaxed and confident, through half distance in 16-41 with Kenyans Judy Kiplimo and Lucia Subano, who has already qualified for the Commonwealth marathon. From 6000m on, however, Harvey intensified the pace relentlessly. England's Bev Hartigan dropped off next, then Murray, her stomach ''completely brick hard'', and she was soon engulfed by three pursuers whom she had dropped earlier. Kiplimo clung on longest, but could not match Harvey's concluding kilometre splits of 3-15, 3-11, 3-9, and a blistering 3-05. Details:
