Although not strictly Lagonda Club it is organised by the Federation of British Historic Vehicle Clubs to celebrate the 1000-mile Trial of 1900, this annual event is held by clubs nationwide as near as possible to St George’s Day, and raises funds for the NSPCC Childline through the sale of rally plaques – purchase here https://www.driveitday.co.uk/shop – £12.50 for a standard plate or £30.00 for a “platinum” plate if you wish to donate a bit more.
Look out for notifications from your regional representative with details of local events in support of Drive It Day.
