Red Pants Boy (RPB) really, really wants to win a running race. But try as he might, his bum is slowing him down. What can he do? Find something to move his bum along, of course!

And while he?s working out, a whole lot of other folk join him. After some training he?s off ? on a cross-country race near home. Think he?s set up to win? There?s a twist to this tale, involving his wee dog friend crossing the line ahead of him by the tip of an ear ?
