HII I CHOSEN THE TOPIC NAME OF MARATHON
Marathons are 26.219 miles long (42.195 kilometres).  That's too far for me to run.  Have you been in one?
YES.BUT I LIKE VERY MUCH
More than 800 marathons are held in the world each year, so many must love to run!  
MOSTLY IINTEREST TO PARTICIPATE
Even though it was one of the original modern Olympic events in 1896, I still get tired just watching people run.  My husband enjoys it, but it looks like pure agony to me.
OH ITS VERY INTERESTING.MY HUSBAND ALSO ENJOY THIS MARATHON
