Imagine a sport that never ended. A football match that goes far beyond ninety minutes or a tussle at Wimbledon that lasts into the night.
Actually, anyone who watched Andy Murray's efforts last year will be more than familiar with the latter hypothesis, but the reason such contests have to come to a close is because of our own fragility. Humans need rest.
One sport that has no such limitation is bowling. Beyond that initial exertion to set the ball in motion, momentum takes care of everything. In fact, if you added the odd slope into the equation, there's a good chance that ball would never stop rolling.
And that's exactly what Downhill Bowling (as the title suggests) attempts to do: it's the bowling battle that doesn't end.
