Dave and Verity travelled from their home in Spain to join the other walkers in tribute to their daughter.
The walk started at Tower Hill and ended at Buckingham Palace.
All proceeds from the walk will go to The Sick Children's Trust, which provides accommodation for parents to enable them to stay near their sick children. This organisation was a great help to Verity, enabling her to stay near Ruby in hospital in Cambridge.
A JustGiving page was opened with the aim of raising £1,000. The current total on JustGiving stands at £1,525. This is enough to sponsor a room at one of the Trust's houses for three months.
When the sponsor money for walkers is added, there is every hope that we will reach a superb total of £2,000.
The JustGiving page is open until 31st May. If anybody else would like to support this worthy cause. You can find out more HERE
