The 16-year-old games volunteer from South Woodford has Usain Bolt's black cap, the one the Jamaican sprinter wore before cruising to victory in a 200m preliminary on Tuesday night.
Hoy's team got assigned to the 200m and Hoy luckily drew Lane 5 out of a hat. That turned out to be Bolt's starting lane. Hoy was waiting at the starting line with a bin to collect Bolt's things.
"As he came out, he kind of went to me, 'What's up?'" said Hoy, who then pounded fists with the sprinter. "As he took his hat off, I went, 'I like your hat.' He went, 'Oh, do you want it?' And that's when he gave it to me."
Hoy has since put the cap on, shown it to friends and family, and even displayed it on his Facebook page. He brought it back to the stadium on Wednesday ready to show off some more.
"I can't put it into words," he said. "I'm still buzzing now from it."
