BHF income generation team member Karen Gray said the event would target 20 to 30-year-old singles and be promoted through national and consumer media.
A media relations campaign beginning this month will target the national and London news media. 'Feature coverage will be a key
element and we are aiming to promote participant case studies and celebrity involvement,' Gray said.
The BHF has lined up TV presenter and 'flirt expert' Tracey Cox to support the walk. She will also compile flirt tips and record a message for a Flirt Walk hotline, Gray added.
If successful, the charity plans similar events across the country.
The Valentine's Day appeal is aiming to raise £1m to fund 30 new BHF nurses. The charity is hoping that as well as creating fundraising opportunities among a younger age group, the walk will also generate awareness of the work done by its nurses, and boost its profile.
