Jody Cundy has revealed his disappointment at being disqualified from the C4-5 1km time trial.
Cundy was refused a restart after slipping out of the starting blocks, with the judges ruling a rider error rather than a technical issue.
"I've wasted four years of my life to ride in front of 6,000 people," Cundy said.
"Do you know what it's like to dedicate four years of your life? I can't even express it. I'll never ever get this opportunity again, never, ever. What am I supposed to do now?"
Cundy's teammate Jon-Allan Butterworth eventually secured the silver medal in the competition.
