Jody Cundy told Paralympics GB; "It feels like somebody’s died. They haven’t; I’ve just missed a bike race. I’ll come back tomorrow.
"Although the 4km Pursuit isn’t my favoured event, I’ve won a bronze medal at the last World Championships and a silver the time before. I’m in good shape, so there’s no reason why I can’t try and make a medal final. Then we’ll see what happens after that."
A distraught Jody Cundy protested and boos rang around the velodrome after the cyclist was denied a restart in the one-kilometre time-trial.
Derek Derenalagi will compete tonight in the Paralympic Games, five years after he lost both his legs while serving in Afghanistan.
Martine Wright has said described representing Great Britain at the Paralympics as "one of the proudest moments I've ever had".
