When green grass begins to turn yellow, the swallows begin to fly to the warmer places in groups, the golden leaves fly gracefully to the ground, those seem to tell us that, autumn has come.
Autumn is a harvest season, also it's the best season to do some sports, in which i think to travel with a bicycle is very exciting. When you ride in a highway which has countless trees stand both sides, ring the bell, pedal smoothly with remarkable speed, you have such a feeling like flying. In the way, you can enjoy the non-urban scene which interests us so much, also, you can taste the traditional culture. Autumn is the best season for cycling. It's neither hot nor cold, and it's seldom to rain, for cyclists, that's an ideal weather. I had such activity a few days ago, the route was, from Hangzhou to Huzhou, then returned. I spent two days to cover the distance.
Recently, a boy, the member of a cycling club, has achieved a goal with a route, from Hangzhou to Lasa, Tibet. The whole distance is about 3700 km. We can imagine, how much frustration he met and how much difficulties he overcame in the journey. Of course, the scene he saw in the way couldn't be enjoyed by ordinary people. Which excits us more is, in Tibetan region, he met a German, who rode a special bicycle from Germany. When he arrived China, he has completed a distance of 17000 km, and the next destination was Japan. It was his plan to ride around the globe! I love autumn, I love cycling.
