I will never forget how much more freedom I experienced all of a sudden when I got my guide dog, Baldwin from guiding eyes for the Blind. That was approximately the time when Guiding Eyes started to train running guides. This means that a blind or visually impaired person can take up running as a sport and do it independently with a guide dog. The white cane is not for running, it is simply dangerous.
One could ask, why not just run with a regular guide dog? After all dogs enjoy running. This is why it is not possible: a guide dog by default is trained to recognize and avoid obstacles at a walking speed. When one would run with a guide dog, practically it would ask the dog to do something she has never been trained to do. It would be confusing for the dog and dangerous for the blind person. During the training program, Guiding Eyes does ask dog handlers not to run with their dogs while guiding, unless the dog has been specifically trained for that. By default, Guiding Eyes does not train running guides, but anybody can request one.
