The Three Peaks Yacht Race is held each year in June in the United Kingdom since 1977. It is based on an idea of Bill Tilman, who had advocated a Three Peaks Challenge route without using motorised transport. His doctor, Rob Haworth, with colleague Merfyn Jones developed the idea into a race.
Bill Tilman passed away in 1977.
