A
I started running half marathons(马拉松) when I was a teenager. I'm almost 70 now, so I've been doing them for 50 years.
I used to run around 15 races every year and when I was in my thirties, I got quite good at them. I think my personal best was around 1 hour 17 minutes. These days I run about five races a year and my time is quite a little longer. At my age, I need more warm-ups, but it's well worth all the work.
Why do I still run half marathons? Firstly, I'm keeping myself fit. My doctor told me that I was healthier than most people half my age! But the real reason why I love the sport so much is the people I meet. I get to know other players and I've made many good friends over the years.
I now spend quite a lot of time visiting schools to get children interested in sports, especially running. The kids always ask me many questions. Many of them can't believe that I'm the same age as their grandfathers. Sometimes I invite them to run a five-kilometre race with me, but not many of them can beat me!
