European 10,000 metres champion Jo Pavey has withdrawn from this weekend's Great Scottish Run after suffering from heel pains.
Pavey, who made history at the European Championships in Zurich in August when she became the oldest female to ever win a gold medal, was due to be the race's headline competitor but revealed she has had the niggling injury for the last few days.
The 40-year-old's decision leaves Ethiopia's Haile Gebrselassie as the main attraction for the fans.
Gebrselassie, a two-time Olympic champion, widely considered as one of the greatest long-distance runners of all time, will be running in the race for the second successive year.
His time of 61:09 from 2013 is the quickest ever recorded by an athlete over 40 and, he will certainly be one of the favourites heading into this year's event.
Asked if he thinks he can improve on that time, Gebrselassie felt certain the weather would have a part to play. "Who knows?" he was quoted as saying on Athletics Weekly.
"The weather was not bad last year but there was a little bit of rain towards the end and it was a little bit windy in another part. So maybe, with better weather this year, I can run faster."
Australia’s Michael Shelley and Stephen Chemlany of Kenya are likely to be his main challengers for the win. Shelley won Commonwealth gold in the same Scottish city earlier in the year, while Chemlany has a 26.2 mile personal best of 2:06:24.
Despite Pavey's absence there will still be a top-class women's field, too, with Ethiopia’s Tiki Gelana, the Olympic marathon champion from London 2012, and Edna Kiplagat of Kenya the pre-race favourites.
