I do 3 to 4 marathon a year and enjoy that every time. Even if it's very hard.
I have watched a few marathons on television, I myself have never partook in one. I can only imagine how had it must be.
Yes it is. Especially when we come near the end
I am sure there are a great deal of marathons every year, 800 or more of all different lengths. I would also think different skill levels as well such as recreational athletes to full time experts.
