The presentation discusses the annual British Heart Foundation London to Brighton bike ride, which raises money for charity. The 55-mile route passes through London suburbs and countryside, with the challenging Ditchling Beacon climb. Over 30,000 cyclists participate each year, raising over £40 million for heart research and patient care since 1980. The presenter competed in the ride last year, finishing in the top 30 out of 800 riders with a time of under 4 hours.
