Hurdler Chris Robinson suffered from an awkward wardrobe malfunction at the Golden Spike meeting in Ostrava. The 24-year-old still managed to win the race, despite his penis falling out of his shorts with 250m to go.

While 200m sprint sensation Gout Gout made headlines in Ostrava for his blistering speed, fellow track star Robinson stole the thunder after an equipment blunder during the 400m hurdles event.

The American, who is a 4x400m hurdles world champion after winning a gold medal at the World Athletics Relays in May, was aiming to add another title to his name in Czechiaon Tuesday.

Robinson got out of the blocks well and started making ground on his opponents on the back straight before his manhood began getting in his way.

The 24-year-old could constantly be seen adjusting his shorts, aiming to fix the problem, and all the while he was sprinting himself into contention.

He clattered into the last hurdle and, even with just metres left to run, was still adjusting his shorts before performing a forward final lunge to take the event with a brilliant 48.05, considering the ordeal he had gone through.

Robinson lay on the ground after being first through the line, staring up sheepishly at his opponents, knowing that his race had been marred by an unfortunate equipment failure.

Broadcasters airing coverage of the Golden Spike were forced to apologise to the millions who had tuned in to watch action get underway at the Metsky Stadium.

Matters then got worse for Robinson, as his win was, of course, replayed on TV, and a close-up, front-on angle was aired of the final 50m, with his manhood on full display.

"That's a brilliant run by the American to be constantly adjusting certain parts of his equipment and possibly his anatomy down the home straight there around that top bend there," said World Athletics commentator Tim Hutchings after the race.

"He hit that ninth hurdle hard. He was having an equipment failure there. I think that is probably the politest way to put it. There hasn't been time to censor them, but well done to Chris Robinson for battling a problem that does emerge occasionally.

"Perhaps in a race every two or three years you see scenes like this from men and women with parts of their equipment failing," he added. "It can make it very, very awkward, but that was a stunning effort to stay out in front with all that going on."

Elsewhere in Czechia, 17-year-old Australian Gout lowered his own national 200m record with a brilliant 20.02. He was bullish after the race, claiming that he would soon break the 20-second barrier.

Pole-vaulting legend Armand 'Mondo' Duplantis was also in action and set his sights on a new world record height of 6.29 metres. The current world record holder and Olympic champion, who bested his own world record feat earlier this month with a 6.28m, could not extend the record further, only clearing the 6.13m mark.
