I started running half marathons(马拉松)a long time ago. A half marathon is 21 kilometers, by the way. I' ve tried a few full marathons, but 42 kilometers is a long way and I prefer the shorter distance(距离). I'm almost 70 now, and I' ve been doing them for over 50 years, but I still get the same excitement at the beginning of each race as I used to.
I don't run as many half-marathons as I did. 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, which was only ten minutes over the world record back then. These days I run about five races a year and my time is quite a bit slower. At my age you need a lot more preparation and your body doesn't recover(恢复) as quickly, but it's well worth all the hard work.
There are two main reasons why I still run half marathons. Firstly, it means I'm keeping myself fit. My doctor told me that I'm healthier than most people half my age! But I think the real reason I love the sport is the other people you meet. You get to know other athletes(运动员) and I' ve made many good friends over the years. The crowds of people who wait on the sides of the streets clapping and shouting as you run past are amazing. I get more and more support the older I get!
I now spend quite a lot of time visiting schools to get children interested in sport, especially running. I think it's really important to get involved(参加) at an early age. It makes it so much easier to keep doing it the older you get. The kids are always interested and they ask me lots of questions. Many of them can't believe that I'm the same age as their grandfathers. Sometimes I invite them to run a five-kilometer race with me but not many of them can beat me!
