The potential impact of shortening matches will be the hot topic in Cancun between September 4 and 6, as the sport's leaders meet in the Mexican city to consider the best way forward for curling.

At the end of the 2018-2019 season, the World Curling Federation (WCF) Board launched a "Maximising the Value" initiative which is investigating the benefits and consequences for the federation, its athletes and member associations.

"Since the introduction of mixed doubles at the Winter Olympic Games the need to comprehensively consider the length of curling games at the top level has become increasingly clear," said WCF President, Kate Caithness.

"A variety of views are held on this topic; therefore, involving our member associations in this process is essential. 

"The Congress in Mexico is an opportune time to continue consulting with them."

The formats of the new 20-team World Mixed Doubles Championships and its open entry qualification event will also be addressed by representatives of 61 member associations, who will vote on rule changes and clarifications.

Last month, the WCF announced the inaugural World Mixed Doubles Qualification tournament would be held at Greenacres Curling Club in Scotland between November 30 and December 7.

It will qualify four countries for the 2020 World Mixed Doubles Curling Championship in Kelowna in Canada.

There has been no qualification tournament previously with the competition open-entry. 

Vice-president for Europe Bent Ramsfjell from Norway and Japanese Board director Toyo Ogawa will both stand for re-election to their roles at the Congress.

Each will stand unopposed for four-year terms.

Caithness added: "The Congress and Annual General Assembly will allow World Curling and our member associations to consider curling's position in global sport and address the best route forward for its growth. 

"I am looking forward to meeting friends and partners in Mexico for another productive Congress."
