I love to go running, Ive even been wanting to join a marathon but dont know too much about it though. 
that's awesome! Running can refer to any of  a variety of speeds ranging from jogging to sprinting
Yeah I suppose I'm more of a jogger, Do you know how many more calories a person burns running compared to walking? 
It depends on a person. some people can burn more by speed walking. 
Thats interesting. I generally jog in the mornings to prevent myself from getting sunburn. Do you do any jogging? 
I don't, for some reason i really hate running, it's so boring. I've read it is assumed that the ancestors of humankind developed the ability to run for long distances about 2.6 million years ago
thats neat, I always knew there was a long history of runners, Say when was the first olympics for running held? 
you won't believe it. first recorded olympic games took place in 776 BCE
