British Takeshi's Castle type show
I'm looking for identification of a show that I watched as a small child in the 1980's. From what I remember is that the show was similar to the popular Takeshi's Castle show in Japan.
I remember people dressing up in horse costumes, vegetables, and even the Royal family, namely the Queen. They were racing or doing some other sort of timed competition. I think it was a British show, but it could have been an Australian one too. Any information would help.
