It was a day of double disaster for Hong Kong as the men's 4x100 metre relay team dropped the baton in the final.
HK were favoured to take gold, just as they were in the cycling road race. A gold for either would have seen Hong Kong surpass their best-ever medal tally at the National Games, but the athletes finished last after Lai Chun-ho dropped the baton in the second leg.
A dejected Lai, said he couldn't explain exactly how he managed it. "I won't complain because we have to accept whatever happened during the race," he said.
"I don't think this is the end of the world. We did our best in our preparations and there were a lot of things out of our control."
Tang Yik-chun, who ran the first leg and passed the baton to Lai, also had no idea how the changeover was flubbed.
"We made a successful exchange and then Lai dropped the baton after running a few metres," said Tang.
"We have never dropped the baton in competition. This is the first time. Timing-wise, I'm sure we could have beat Guangdong, but there is nothing we can do now."
Guangdong, Hong Kong's main rivals, won the race in 38.73 seconds, followed by Sichuan and Zhejiang. Hong Kong, the reigning Asian champions, were last in 47.56 seconds.
Coach Yu Lik said the men's team, which also comprised Ng Ka-fung and Tsui Chi-ho, had to put the disappointment behind them as they still have the East Asia Games in October.
"I didn't see clearly what happened as I was sitting in the spectators' stand," he said. "It's never happened before in a competition, but this is part of the game."
