The Scottish Masters Athletics International, (SMAI) is organized and operated to foster international amateur sports competition for charitable and cultural purposes. We are the exclusive sanctioning authority and host for the Masters World Championships (MWC) for the traditional Scottish Highland Games athletic competitions called the "Heavy Events." These events include stone throws, weight throws, hammer throws, caber toss, sheaf toss, and similar traditional feats of strength.
The MWC is an annual amateur competition with the location being determined by application from host organizations of highland games sites across the globe and the locations of the competitions are determined by the SMAI. The MWC competition is open to all athletes over 40 year of age with proper qualification as determined by the SMAI.
