Mo Farah is highly unlikely to compete at the Commonwealth Games in Glasgow next year after deciding to prioritise the London Marathon.
It is a significant blow to Games organisers as the reigning Olympic and world 10,000 metres and 5,000m champion was expected to be one of the star attractions.
The 30-year-old insisted he can focus only on one race next year, but offered faint hope he could be involved in Glasgow. "I don't know. It just depends how I come off that marathon," Farah said. "My aim is to do the London Marathon and that is what I am fully focused on. It's a bonus if I do it, but it is not on my list."
