JJ will now be supporting Emap events such as Your Horse Live, the London Motorcycle Show and Go Fishing. Activity will include creative and artwork; advertising; targeted emails and direct marketing; PR; guerrilla marketing; and promotion and digital activity.
Work begins on the Motor Cycle News Live events in October.
The agency won the brief after a pitch, although it has been working with Emap for a year providing PR support for titles including Motor Cycle News and Parker's.
Nick Bradley, marketing and strategy director for Emap Peterborough, said: "We chose JJ because we know from past experience that they work seamlessly alongside our internal team to deliver well thought through, truly integrated, hard-hitting campaigns."
