“The dog makes the run,” Tim Malo said. “They jump over everything. I’m just dragging my old body behind them.”
Mr. Malo was recruited to race by his friend, Kathy Watson, from Sale Creek, Tenn. To prepare, Ms. Watson and her border collies, Rolex and Jack, spent three weeks dock-diving, a sport where dogs launch off a platform to chase toys in the water.
But when her husband declined to run with her — “because he’s sane,” she said — she asked Mr. Malo to team up with Jack.
