Star sprinter Su Bingtian ended a busy season by helping win the gold medal in the men's 4x100 meters relay at China's 14th National Games in Xi'an, northwestern Shaanxi Province, on Friday.

"Time for vacation!" the 32-year-old Olympian remarked after leading the United Team, China's Olympic relay team, to the title in 38.50 seconds in heavy rain.

"We couldn't do a normal warm-up because of the weather, so I am happy we won and no accidents occurred. This is my last national games, and I am glad to have a happy ending," he said.

"I can't wait to go back home and see my son. I have not seen him for five months."  

At this year's Tokyo Olympic Games, Su became the first Chinese to qualify for the Olympic men's 100m final, setting an Asian record time of 9.83 seconds in the process.

After quarantining back in China, Su still maintained his good form at the national games, dipping under the 10-second barrier once again to win his first 100 meters title in the games, but missed out on the men's 4x200 meters relay gold with the Guangdong team.

"My national games debut was in 2009, and this is the fourth time I am here. From today's event, I can see a bright future for Chinese sprinting," he said. "The top four in the final all broke the 38-second barrier, which really inspires me, because only the national team could do so a few years ago.

"Chinese sprinting is on the right path, and the national games is an important stage for promising sprinters for their Olympic Games preparations." 

Teenage gymnast Wei Xiaoyuan, an alternate on China's Olympic Games roster, rallied to take the women's all-around title on Friday.

The 17-year-old from southern Guangxi Zhuang Autonomous Region won with 55.064 points, edging national teammate Ou Yushan of Guangdong by 0.099 points. Luo Rui, another alternate at Tokyo Olympics, settled for bronze with 54.866 points.

Wei produced an excellent performance on the uneven bars to lead the competition after rotation three. Her score of 13.266 in the floor exercise held off a strong challenge from Ou, whose 13.500 points were not enough.

"Though I was a little nervous on the uneven bars and floor exercise, I managed to finish the competition without big mistakes," Wei said. "The gold medal boosted my self-confidence since I have little experience of big events."

Wei's attention will now turn to the 50th World Gymnastics Championships in Kitakyushu, Japan, in October.
