Brown set up camp next to his rowing boat in Exchange Square, yesterday at 5pm, where he will row for the next 48 hours, until 5pm on Friday September 30th.
The spectacle will be able to be seen from the platforms of Liverpool Street station and Brown will be fielding questions from passers by, in an attempt to raise public awareness of his mammoth challenge to row the Atlantic on his own.
The solo row will begin on December 4th from the island of Gomera, ending in February on Barbados. Out of each 24 hours, 16 will be taken up with rowing, with the other eight used for eating and sleeping.
So far, Brown has raised just over £50,000 for the Toy Trust and Help a London Child, with the target being £100,000. If you can help him reach that goal, please visit www.rowtheatlantic.com.
