Former world track champion Kwok Ho-ting is considering quitting cycling after becoming disillusioned with the sport.
A key member of both Hong Kong's track and road-race team, Kwok would be a major medal contender at next year's Incheon Asian Games.
But the 25-year-old expressed his desire to quit yesterday, possibly to return to university.
"I feel very tired after having cycled for 14 years," he said after finishing fifth in yesterday's East Asian Games individual road race in Tuanbo, southwest of Tianjin.
"Not because of failing to get any medal here. The thought's been around for a period. Before, I always cared about the result of each race but now it seems I just give my best and winning or losing has little to do with me.
"Maybe I have reached a certain stage of life and it's time to rethink my future whether I should stay in sport or look for other options."
He admitted the recent departure of another Hong Kong team member, Choi Ki-ho, had an effect on his decision.
"We have been working together for a long time and his decision to leave has upset us," he said.
Choi, widely regarded as HK's most talented road-race rider after Wong Kam-po, plans to join a pro team in Europe.
Head coach Shen Jinkang said he had given Kwok a week off to think carefully about his own future.
"He won't be involved in our next two races as it won't make any difference with or without his participation due to his present state," said the coach.
Meanwhile, in yesterday's women's race, Meng Zhaojuan and Diao Xiaojuan were fourth and fifth respectively in the 43-kilometre race. "We have to work as a unit in road races or it will be very difficult to succeed," said Shen. "[Winners] Taiwan displayed a high level of team work today."
In badminton, Lee Chun-hei and Chau Hoi-wah were beaten by China's Xu Chen and Ma Jin 21-13, 21-13 in the mixed doubles final.
In karate, Chan Ka-man and Cheung Kwan-lok won bronze medals in the women's 61kg and men's 55kg respectively.
