Maydayrun is an annual event in England among other countries that takes place on the first bank holiday Monday in May. It is also often referred to as "MayDay Run" or "May Day run".
The event involves thousands of motorbikes taking a 55-mile (89 km) trip from south of London (Locksbottom, Farnborough, Kent) to Hastings Seafront (Hastings, East Sussex, TN34), coinciding with the Jack-in-the-Green festival on that day. The event has been taking place for over 40 years now and has grown in interest from around the country commercially and publicly.
The event is not an organized as such, only the police manage the traffic, and volunteers manage the parking. Hastings fills up with tourists and bikes by about 11 AM, and the A21 road from London serving Kent and the South coast is the used road which, as a result of the trip, is severely congested during the event.
