How much does it cost to take part? The registration fee for early birds is £15 adults and £8 for 8-17 year olds. The Early Bird offer ends 7th May. The cost will be £20 per adult and £10 younger walks thereafter until midday on 16th June 2019. This covers the cost of administration, refreshments on route, your medal, and your certificate of achievement at the end. The registration fee ensures that all the sponsorship money you raise can go directly to helping our patients and their families, friends and carers.
