A man's 100-meter sprint in 27.08 seconds might not be interesting, but it's different when he's 102 years old.

Thai athlete Sawang Janpuram, famous for being the oldest runner in the Southeast Asian country, has competed 4 times in the annual Thailand Professional Athletics Championships.

And at the weekend, at the 26th edition of the championship held in the southwestern province of Samut Songkhram, he won all the gold medals in the 100-105-year class, surpassing all competitors in that age group.

When asked about the secret behind his long life, Sawang said, "Exercise has made me strong and good. In addition, exercise helps improve your appetite so that you eat well too."

Sawang walks daily with his 70-year-old daughter, Siripan, doing simple household chores such as sweeping fallen leaves in the garden.

But before the competitions, he was upping the ante, training twice a day for a week at a local stadium with his daughter.

The training paid off, as Sawang's time in the 100m this year was a personal best and a new record for his age group in Thailand.
