The annual Liffey Descent is perhaps the most famous long-distance rough water race in the world. Demand to compete in this race is such that a limit of 1,200 competitors was imposed in 1995 for safety reasons
While the traditional form of marathon racing takes place on a closed flatwater course, a more extreme version of racing has evolved, involving racing over marathon distances on rivers where there are obstacles such as weirs and rapids to be negotiated. Such events combine the physical demands of marathon racing with the white water skills of other racing disciplines. The Irish environment and climate lend itself superbly to the requirements of these two aspects of marathon racing. We have many miles of inland waterways with numerous rivers providing an array of challenging rough water races.
