Intresting, makes me wonder why anyone would choose marathon, but it is pretty good. Would be much better if you chose the beginning theme instead, i really dont like the song all that much, needs some, but still good. Try taking out that sort of groovy feel to it, and improve the chopped of style ending if you want a greater song :D
Haha nice! Reminds me of like.. a spy or something. Or sly
