Partners on and off the ice talk about the tensions and joys of competing alongside the ones they love at the Winter Olympics

Every Olympics has its love stories. Usually, they’re all about the quantities of free prophylactics being handed out in the athletes’ village (this year’s edition has an image of the Olympic mascots, the friendly stoats Milo and Tina, on the box). But you have to look a little harder to find the great romances of these Games, which have been on the ice rink in Cortina, where, for the large part of the past week, a trio of married couples were competing against each other in the mixed doubles curling. It is essentially a competitive lovers’ stress test held in front of a live audience.

It’s a peculiarity of the Winter Olympics that there are so many partners partnering with each other in different events. There were two in the ice dancing: the US pair of Madison Chock and Evan Bates won silver and the Italians Marco Fabbri and Charlène Guignard came fourth. Which is all very well. But if you want to see a relationship you can actually relate to, curling was the sport to watch. It’s as if they made an Olympic event out of sharing the front of the car with your partner on a road trip with a map and no satnav.

All stones in Cortina are made from granite found on tiny island in Firth of Clyde and crafted in East Ayrshire

“It takes 60m years and about six hours to make a curling stone,” shouts Ricky English above the whine of the lathes. The operations manager at Kays Scotland is surrounded by wheels of ancient granite in varying states of refinement.

It is a small business with a big responsibility: the only factory in the world to supply the Winter Olympics with curling stones. Competitors don’t travel with their own stones, which weigh about 18kg each, and with 16 required for a game. Instead, this year, 132 stones were crafted in the East Ayrshire town of Mauchline and shipped to northern Italy.
