I participated in a cycling event yesterday. This event attracted cycling lover from all over the city. I was not sure where I found the courage to undertook it, but it could have been the inspiration from the spirit of sportsmanship I witnessed before.

My friends and I began my cycling adventure at 6 am from the eastern side of the lake. The cycling path was lined by a variety of color flowers, many of what I couldn’t identify by name. Looking down on, I noticed lots of falling leaves on the red track. At that moment I realized leaves were so attractive. Of course, this journey wasn’t just the feast for the eyes. It was absolute a physical challenge too.
