CANOEING: Close to 1,000 boats will take to the swollen waters of the Liffey at Straffan today for the annual Liffey Descent - the Grand National of the sport.
Ahead of them lies 17 miles of swirling water including 10 weirs, two sets of rapids, a short portage where the paddlers pick up their boat and run with it, and a treacherous stretch of low-lying branches called 'The Jungle'.
Up front, the K2 team of Peter Egan and Jon Simmons are defending the title they won last year and should make it to the Islandbridge finish in under two hours.
Last weekend, Egan finished 16th at the World Marathon Canoeing Championships in Oklahoma - a best-ever result.
In the women's race in Oklahoma, sister Jenny did even better, finishing seventh, also a best-ever. Last year at the 'Liffey', Jenny won the mixed K2 title paired with Martin Kolanda and she aims to retain the title.
In men's K1, Dermot Hudson (pictured) is the defending champion.
