I have started running in marathons and it's something I really enjoy.
I love running as well, i realize it was one of the olympic events and was started in 1896
Oh wow that is a long time ago. It is a great sense of accomplishment to do it
These days they are used to support causes. Like running for cancer and all that.  800 marathons are held throughout the world each year,
That is a lot. I usually enter them with some work friends and we will go on a Saturday or something. Need to prepare long before that though

Oh I did not know that. Seems like a good story to read.
