So, Mo has pulled out of Glasgow because he is still suffering after effects of his 'mysterious stomach problems a couple of weeks ago' and wants to ensure that he will be fully prepared/ready for the European Championships in August - or is it because he knows he's not in the form to take on the Africans. Me thinks he never really intended to run atGlasgow but to keep himself back for the Europeans where there is not such a high standard of opposition.
And, yes I do know what the effects of an illness can be on training/competition as I am actively involved in athletics.
