BLOCKDOWN is a virtual event, run over 24 hours. Runners run solo or with a team of up to 4 people to cover as many postcodes in the Greater London area as possible. Start from anywhere, at any time and set your own route. You can run for 1, 2 or 3 hours, or choose the full 24 hours to claim as many as you can.

The aim is to run through as many postcodes as possible in your chosen time frame. We will be tracking your journey and counting your postcodes via your phone. Once you have registered we will send you a bib number and information about how to set up tracking.

A full list of postcodes can be found here. You must make sure you are fully in the postcode – putting one foot in does not count. Running a street or block should do it.

Team members can run separately or together, but postcodes will only be counted once for each team. Your score will be the combined total number of unique postcodes blocked off by team members.
