The campaign, created by 141 Worldwide, will be fronted by champion flat jockey Jamie Spencer and will run through the summer.
The work will target existing and potential Racing UK subscribers through a series of press ads supported by direct marketing. Spencer will make personal appearances at race days and media events, and provide exclusive interviews for the Racing UK channel and website.
The flat-racing season begins this week; highlights include Glorious Goodwood and the Epsom Derby.
