In a statement today, former Loughborough athlete Paula Radcliffe has expressed her profound disappointment at not being able to take part in the London 2012 Olympic Games.
"It is hard to know that had the Olympics been six weeks earlier I could have gone out there and run confidently knowing that I was in the best shape I had been in for a while, but I am by no means the first to experience something like this.
"No-one tells us in advance where the limits of our own bodies lie, and pushing these limits is the only way we can ever achieve our highest goals and dreams.
"However hard today is, finally closing the door on that dream, at least I can know that I truly have tried absolutely everything.
"As desperate as I was to be part of the amazing experience of the London Olympics, I don't want to be there below my best. If I can't be there and give it my best, then I would rather someone else who can do that is able to be there.
"I have been through the mill emotionally and physically the past three weeks, cried more tears than ever, vented more frustration and at the same time calmly tried every direction and avenue available to heal myself.
"Now is the time to rest totally, give my body chance to recover and assess calmly what can be done and where I go from here."
