Ray Lewis is officially retired. But if you think that means he's going to spend his first free summer in more than a decade sitting on the beach and taking it easy, you're wrong. Instead of kicking back and relaxing this summer, the former Ravens linebacker plans on climbing Mt. Kilimanjaro next month. He's calling the climb "TackleKili" and he's doing it in order to help bring clean water to kids in Africa.

That mountain doesn't stand a chance! Follow @TackleKili on Twitter to stay updated on the climb.
