National (curling)

The National is a curling tournament that is one of the five events that are part of the Grand Slam of Curling tour, and one of its four "majors".
The event was re-branded in 2025 to the KIOTI GSOC Tahoe to reflect the event being held outside of Canada. The 2004–05 event was also re-branded as the BDO Curling Classic.

Format

Beginning in 2022, the event features 16 men's and 16 women's teams. The top 16 teams on the World Curling Federation's Order of Merit qualify. In some cases a "sponsors exemption" is permitted, in which a local team is picked to compete. The 16 teams are divided into four groups of four teams, and the top eight teams overall advance to a single elimination playoff. In 2021, the event was a 16 team triple knockout event before the 8 team playoff. From 2015 to 2019, the event had 15 teams divided into three groups of five teams. From 2007 to 2014, the event had three pools of six teams each.
