MO Farah will undergo tests to determine the extent of a problem which saw him require medical attention after the bupa Great Edinburgh International Cross Country – a month after collapsing at the end of a race in Dublin.

Farah, who was carried away after finishing second at the European Cross Country Championships in Ireland, again crossed the line in distress on Saturday as he was beaten into third spot by Ricky Stevenson and Steve Vernon.

Paramedics rushed to offer treatment when it seemed there might be a reenactment of the Santry Park incident.

Farah, although unsteady on his feet, remained mobile after the 4km race, but admitted all was not well.

‘‘There’s something not right, I almost collapsed again. Hopefully there will be nothing wrong,’’ said Farah, who started the race at breakneck pace, which saw him leading at one stage by almost 100 metres.

‘‘I’ve got to think positive,” added Farah, who ran out of steam over the final circuit of the race.

Now the 26-year-old Londoner will be having more blood tests to ascertain if there is a real problem before flying off to a high-altitude camp in Kenya tomorrow.

While Farah paid for his impetuous start, up-andcoming 1500m specialist Stevenson – the country’s latest sub-four-minute miler – was in dreamland after his unexpected victory.

The 21-year-old Teessider stormed away in the last 200m to consign Vernon to the runner-up spot for the second successive year.

‘‘A win like this is something you dream about and now it has happened I just cannot believe it, but the feeling’s great,’’ said Stevenson, who can now expect an invite to relocate to Loughborough and join up with UK Athletics’ elite distance running squad.

London Olympics medal hopeful Steph Twell finished a place lower than last year in the women’s event, claiming fifth in her 5.8km contest. But she came away with her confidence massively boosted after mixing it against tough opposition.

Twell, along with European champion Hayley Yelling-Higham, who finished a spot ahead in fourth, fought bravely before losing out on a podium finish behind the African trio of Tirunesh Dibaba, Vivian Cheruiyot and Kalkidan Gezahegn.

Dibaba, the Olympic 5,000m and 10,000m champion, dashed to the front at the start of the final circuit and never looked like being caught. She crossed the line ten seconds clear to add to her 2005 victory at the meeting.

Twell, after a sticky patch during which university exams interrupted preparations for her disappointing European Cross Country outing, was delighted with the outcome, even though she was beaten over the last stride by Yelling.

‘‘I’m happy with my performance,’’ said Twell.

‘‘It was one place lower than last year but it was different opposition and a very strong field.

‘‘With the Africans and European senior women’s champion Hayley in there I knew it was going to be tough, but I wanted to have a strong race.’’ Twell, who switched from English to Scottish nationality last July, added: ‘‘Everyone was really getting behind me, especially when I was working in a group with the Kenyans.”
