Matthew Pinsent presents highlights from Lee Valley as the London 2012 venue plays host to the world's top canoe slalom athletes as they battle it out at the largest global canoeing event outside of the Olympic Games.
It is the first time the UK has hosted the World Championships since 1995.
World champions will be crowned in five disciplines, where success can also secure a country's participation at the 2016 Rio Olympics.
This is a live BBC Two stream starting at 13:45 BST.
