Asked for her thoughts on the 100-day countdown to the Winter Olympics, World Curling Federation president Kate Caithness delivered an emphatic reply: "Beijing will do an excellent job, 100 days can't wait."

Caithness' confidence stems from her experience of the 2008 Summer Games in the capital, as well as what she witnessed at a Beijing 2022 curling test event this week.

"I was very impressed with the layout of the field of play, and was particularly impressed with the new giant screen. They have done an excellent job," Caithness said.

The 170-square-meter screen is one of a number of high-tech products installed at the arena. It is positioned perpendicular to the competition area, displaying the four tracks simultaneously so spectators don't miss any of the action.

Caithness also heaped praise on Beijing 2022's COVID-19 countermeasures.
