"Today I’m offically announcing my retirement and it’s a decision that I didn’t take lightly and I thought about it very hard," said Hoy. "The reason for that is that I thought I’ve got every last ounce of energy out of myself. I got to London and I don’t think people realise how much that took out of me."
Hoy also explained his decision not to compete at the Commonwealth Games. “To try and go on for another year would have been too much and one year too far for me,” he said. “I didn’t want to turn up to wave to the crowd and wear the tracksuit. I wanted to be there to win a medal for Scotland. Because I don’t feel I can do that, I would rather step aside and let somebody else take my place.”
