The Dunwich Dynamo (sometimes abbreviated to "Dun Run" or "DD") is an annual semi-organised, through-the-night bicycle ride from London Fields park in Hackney, London, England to Dunwich on the Suffolk coast. The distance is approximately 180km (112 miles).[1]

The ride takes place overnight, hence "Dynamo". It is usually scheduled to take place on the Saturday night closest to the full moon in July, partly for tradition but also because it is easier to ride by moonlight.[2] The date for DD20 was moved to 30 June/1 July 2012 to avoid clashing with the Olympics. The 2020 edition was cancelled due to the COVID-19 pandemic.
