The Sussex estate hosts some of the country's premier social sporting events - such as motor-racing events The Festival of Speed and the Goodwood Revival and famous horseracing meet Glorious Goodwood.
Pelham will be asked to increase coverage of these events in the business pages of the national media. The brief will also include an aspect of B2B PR to promote the occasions and estate directly to organisations.
The agency won the account without a competitive pitch, having become known to the estate via its work with Walpole - the British luxury trade organisation.
Goodwood won best British luxury brand at Walpole's 2008 awards.
The estate also boasts the luxury hotel, golf course and members club The Kennels.
