Hi have you ever ran in a marathon?
I've never ran a marathon personally.  My dad did when I was just a little kid.  I did run track though.  How about you?
I have not ran one. did you know the marathon has an official distance of 42.195 kilometers?
I didn't know the kilometer distance.  I know it's measure as 26.2 miles in the US.  Interesting that we haven't started using the metric system.  Do you like running over 5 miles?  
I am not a big runner myself. One cool thing i just found out is that the original modern Olympic event held the first ever official marathon in 1896
What a cool fact.  Crazy to think that people have been running that distance for so long.  I like the idea of summer games having multiple events like short and long distance races. 
Yeah! The Summer sports are my favorite to watch and play. One more fact, the first ever olympics had participants actually die from attempting to run such far distances
I wonder if that is why they started spreading the games out every 4 years - too many competitors were dying off??
