The Whitewater Challenge is an annual event that involves navigating a whitewater river in a kayak or canoe. The event is open to all levels of paddlers, from beginners to experts. The goal is to complete the course in the fastest time possible while avoiding obstacles and hazards. The term 'EDDY' is used to describe a circular current of water that forms in a river or stream, often caused by an obstruction such as a rock or boulder. Eddies can be used to help a paddler navigate a river, as they can provide a safe place to rest or turn around.
