FOUR workmates will take on a monster 100km endurance walk to raise money for a charity inspired by a five-year-old boy from Abingdon.

The group from Brand Solutions in Bicester, which specialises in protecting property rights, will walk non-stop from London to Brighton on Saturday and Sunday.

The co-workers were moved to take on the challenge by the story of a client's daughter, Grace Duggan, who died aged eight from treatment complications for a brain tumour.

Company director Andy Hunter wanted to do something to help, so he decided to walk the 100km to raise money for Abingdon charity Blue Skye Thinking, which aims to prevent deaths like Grace's.

The charity was set up by Sally and Andrew Hall in memory of their five-year-old son Skye, who also died from complications from brain tumour treatment in 2014.

Mr and Mrs Hall are trying to raise money and campaign for research into such side-effects to help prevent future deaths.

Mr Hunter said the charity was doing "vital" work to fund research.

He added: "Blue Skye Thinking’s work funding much-needed research in this field is vital, so we wanted to support them.

"They were a cause close to Grace’s mother’s heart as she knew Skye and his mum Sally.

"As a company we like to undertake charity events as most of the staff are quite young and find it rewarding.

"We are looking forward to it with excitement and a bit of apprehension as it is the furthest we all will have ever walked continuously, but the blisters will be worth it for this wonderful cause."

The team for the London2Brighton Challenge will be made up of Mr Hunter, Claire Hunter, Richard Brice and Glen Kavanagh. Alex Turvey will act as a driver.

All the money the charity raises will go into research into new treatments for childhood cancers, with the aim that all children diagnosed with brain tumours will have a better chance of survival and a better quality of life post-treatment.

Mrs Hall, 37, said: "We have had lots of people organising events in Grace’s memory over the last year or so and it is so touching for me personally as I knew Grace and her family after meeting them on the ward with Skye.

"Andy and his team are hoping to raise £4,000 for us.

"This is a fantastic amount and will provide much-needed funds to continue our work so children like Skye and Grace, who are diagnosed with brain tumours, can have a brighter future."

More than 350 children a year in the UK face the news they have a brain tumour but less than one per cent of cancer funding goes towards research into brain tumours – the number one cancer killer in children and teenagers. The cure rates have not improved in 40 years.
