Horseradish, the catering and events division of Chester Race Company has secured a three-year contract with Wales Rally GB worth £350,000.
It will provide hospitality offerings at each stage of the event, including bespoke packages, for more than 500 guests each year.
The deal will start this year when the World Rally Championship comes to the UK in October.
Kate Dawson, head of commercial and sales at Chester Race Company, said: "We're thrilled to be working with Wales Rally GB on one of the biggest events in rallying.
"Showcasing our offering in three separate areas across the event map gives our brand fantastic exposure and we look forward to establishing a mutually successful partnership over the three years whilst serving a satisfied client base."
Ben Taylor, managing director of Wales Rally GB, added: "We are delighted to welcome Horseradish to an altogether different type of horsepower.
"The excellence of their catering and hospitality is already well-known to Chester Racecourse visitors and I believe they will add another dimension to the experience of watching Wales Rally GB in a truly unique and memorable location with first class facilities."
The Horseradish team now serves more than 75,000 hospitality guests each year, across all its venues and events. It provides facility management, catering and event solutions.
Established in 2009 to cater for the 220,000 people visiting Chester Racecourse every year, Horseradish has since secured several contracts with a variety of clients.
These include Speke Hall in Liverpool, Liverpool Cathedral, Chester Town Hall, St George's Hall in Liverpool and the Cholmondeley Pageant of Power, held annually at Cholmondeley Castle in Cheshire.
Earlier this month the firm announced two contract wins at summer events in the North West.
