If you haven't heard about it then the best introduction would be reading the book "The Best That Money Can't Buy" (The Venus Project sells it on their website). Otherwise you can scratch a bit of the surface of the project by watching their recent documentary on YT "The Choice is Ours". Their documentaries are always free to watch. They don't sell them.

You should write about it. I can't imagine someone running a marathon. It must take years to get to that form and mental perseverance. Forget about ultra marathons :-)
I hardly run 15 km atm :-)

Yes Spartan Race is an obstacle course. Mud run like :-)
