Seven-year-old Charlie Simpson, from Fulham, West London, has raised a whopping £75,000 for the Haiti Earthquake Children's Appeal.
Simpson got on his bike and cycled for five miles, originally aiming to raise £500 for the earthquake-struck country. His efforts quickly gathered publicity and donations have been sent from across the world.
