Hundreds of runners of all ages and abilities, including celebrity supporters, are expected to join in the 5km fun run, which will be followed by a picnic and family entertainment for those who took part.
All money raised by sponsorship will go to the Great Ormond Street Hospital Children’s Charity, which provides funding over and above what it receives from the NHS, to help keep the hospital at the cutting edge of child medicine.
The charity is currently looking to raise £170million to replace outdated buildings on the site, providing more space and better facilities for research and treatment.
