I like running.  A run can range from a jog to a full sprint. Do you run also? 
I used to like running but my knees don't work that much anymore. How often do you run?
I run three times a week. Running is associated with the characteristic where all the feet are off the ground. 
I see, do you need any special equipment to run?
Not really.  Just good sneakers.  Running is characterized as the world's most accessible sport. 
Yea its important to wear comfortable shoes to run. Is running a good exercise? 
I think so. Running came about from religious festivals in various areas back in the day. 
I had no idea! Is running characterized by the use of muscular tendons? 
No running is the act of having both feet off the ground. With walking there is always one foot touching the ground.
