Some 60,000 spectators will be at the new Lee Valley White Water Centre to witness the Olympic slalom canoe events.
Helen Reeves, BBC Sport
"The canoe slalom course is packed full of excitement. Something is always on the edge of going completely wrong. David Florence is one of the top British paddlers - he's the Olympic silver medallist in his C1 event but also now competes in the C2 with Richard Hounslow, picking up world championship medals. It's possible they could come away with double medals, which would be a canoeing first. In the men's kayak, keep an eye out for Italian Daniele Molmenti and Slovenian Peter Kauzer. Lizzie Neave is the only women's entrant for Team GB and has a chance of competing for a medal in the K1."
The sport's appeal is not hard to understand; it provides a real test of speed and strength and is visually spectacular too.
An estimated 13,000 litres of water a second powers down the course - enough to fill 75 bath tubs every second while negotiating up to 25 gates on the 300m course. It is a totally different sport to canoe sprint, where pure speed on a flat course is the key.
There are four events in all, the men's canoe single (C1 men), men's canoe double (C2 men), men's kayak single (K1 men) and women's kayak single (K1 women). In canoes, competitors use single-bladed paddles; in kayaks, competitors use paddles with blades at both ends.
It is a sport dominated by Europeans, with 10 of the 12 medals at the Beijing Olympics going to European competitors. Among them was Great Britain's David Florence, who won silver in the men's C1.

Paddling uses most of the muscles in the arms and legs, with n hour's canoeing burns approximately 287 calories.
The strain of fighting against the power of the water leading to an increase in upper arm, forearm and chest circumference and grip strength.
A Manchester Metropolitan University study found that regular canoeists possessed superior heart strength enabling them to pump blood around the body more efficiently.
As several canoeing disciplines are carried out in pairs, it is an excellent way to develop communication skills and learn to work effectively with other people. Clubs also offer a variety of social events beyond simply taking part in the sport.
If you haven't canoed before, a starter course is a good idea. There are clubs and watersports centres all over the United Kingdom, with some offering slalom teaching for mixed groups or for novices.

If you are new to canoeing and kayaking,
it is not necessary to purchase equipment straight away. Very often clubs and centres will have equipment that you can use, under supervision.
After you begin to paddle more regularly you may then wish to purchase some of your own equipment such as a helmet, spray deck, buoyancy aid, paddle and even a canoe.
There are approximately 4,500km of navigations and canals in the UK that can be paddled on with the
White-water centres also offer a variety of exciting sporting and team-building activities.

Great Olympic moment

Modelled on slalom skiing, canoe slalom involves timed runs down a white-water course.
Red gates must be negotiated upstream, while green gates must be negotiated downstream.
Touching a gate adds a two-second penalty to the overall time, while 50 seconds are added if a gate is missed altogether. As well as time penalties, athletes can be penalised for other infringements such as being judged not to have started or finished correctly.
Each second counts for one point, with penalties added at the end, and the winner is the competitor with the quickest time after penalties are accounted for.

Canoe Slalom began in Switzerland in 1932 and was first performed on flat water before later switching to white-water rapids.
The first known competition took place in 1933 but, although canoe and kayak racing became full medal sports at the 1936 Berlin Games, canoe slalom only made its debut at the 1972 Munich Games and was then dropped until returning in 1992.
