"Things were going well, I didn't think for a minute anything was wrong," he said.
"It just came on suddenly and, when it was painful to even walk, I knew I was in trouble."
Butcher said he was "gutted" when he learnt of the seriousness of his injury and he quickly realised there was no chance of recovering in time to compete in Poland.
"You can't go into an event like that without being totally fit and ready, and I knew that was never going to happen. There was no option but to pull out."
Medical advice to Butcher was to stop running for at least 10 weeks. At long last, the wait is over and he is slowly starting to get back into the groove again.
Typically though, the man has not let his frustrations get the better off him.
He is already looking forward to his next endurance competition, although he admits that probably will not be until about March next year.
"It's going to take a while to get back into shape but we'll get there, no doubt about that."
