Running is pretty fucking awesome.
Marathons do put quite a bit of stress on your body though. Without the proper training, they can really wreck you.
Going in to a marathon after training half assed would be like attempting a 1,000 lb. squat when the most you've ever lifted was 400.
That would probably kill you too.
And why does the media care to painstakingly edit running deaths in a conspiracy to make running look good? Seems like a complete waste of energy to me.
