Wildwater racing is a blend of skills from 3 areas:
1. Flatwater skills - the ability to execute a good froward stroke, to propel the boat quickly and effiicently. Additionally the ability to train well, to improve your conditioning to perform and enjoy WWR more.
2. Core whitewater skills - the ability to read and understand water, and to execute strokes to propel the boat in WW.
3. Core wildwater racing skills - the ability to take the core flatwater and whitewater skills, and apply them to a wildwater racer.
The wildwater racing manual provides a great resource of information on the skills required, and how to develop them.
