What's your hobby?

My hobby is running. Every morning I jog in the sunshine. It helps me to relax and stay healthy gives me relaxation and healthy, and every year I participate in several marathon events. The most recent event was is Singapore's sundown marathon. Do you have any hobbies? Will you share with me?

Great piece of writing! It's amazing that you run marathons.

Sometimes you use a comma ( , ) when you should use a full-stop ( . ), which is also called a period. You could revise the difference between the comma and full-stop.  

I like rollerskating and reading books. :)
