Irish cyclist Martyn Irvine admits his chances of a medal in the men's omnium are over but has vowed to put in an improved performance on Sunday.
The 27-year-old from Newtownards had a disappointing day in the velodrome, closing in 10th position after three of the competition's six events.
He started off with a ninth-placed finish in the 250m flying lap, clocking 13.504 seconds, and was then sixth with a score of 47 in the points race.
But his podium ambitions took a hammering when he was the fourth rider out of 18 to exit out in the elimination race.
"It was a reality kick," he said. "My aim was to be top six or seven going into the last day and I feel a medal for me was doable.
"You dream of a medal, there's a lot of hard work and you hope for the best but it isn't to be.
"In the endurance side I feel I've been at my best and right up there but it's just about tactics and my rider-type lets me down. I'm not a sprinter and that's what the elimination race needs.
"Bunch racing and sprinting lets me down a heap."
Although Irvine was clearly upset as he left the track, he has vowed to prove his quality when Sunday's events - the 4km pursuit, the 15km scratch race and the one kilometre time-trial - get under way.
"I'll give myself a shake, get up and put a bit of fire in my belly and for tomorrow," he said. "Tomorrow is my stronger day. I know I can climb a few places, I'm always in the top four or six for the strength and endurance events."
