Shadow Sprint

A giant golden stripe of morning light sliced right through the window and slapped the floor! I hit the yellow track at maximum throttle! WHOOSH! And then I saw it—a massive, pitch-black copy of me stretched high up the white wall, mimicking every frantic knee kick! A challenger! I flicked left, it flicked left! I threw my hands up, it threw giant stick arms to the ceiling! I revved my feet and went all out, racing my giant shadow twin neck-and-neck down the razor edge between light and shade! Clatter-clatter-CLACK! We tied for first place right as I skidded into the cold metal legs of the radiator!
