Siblings are taking on a marathon physical challenge to raise money for the charity which did everything possible to save their dad's life.

Brother and sister Kye McCarthy, 34, and Sian Chambers, 36, will be walking from Bethnal Green to Witham next month to raise money for the Essex and Herts Air Ambulance Service.

On June 26 last year, dad Kenny McCarthy suffered a heart attack at his Witham home.

Despite the best efforts of the paramedics, ambulance officers and air ambulance crew he passed away, aged 63.

Mrs Chambers said: "Since he passed away we have wanted to do something for the air ambulance.

"We held a collection at his funeral but we wanted to do something a bit more so that hopefully we can help them save someone else's dad in the future.

"We wanted to do something a bit different. Lots of people do half marathons of sky dives so we decided to do something which meant something to family as well."

The walk will kick off from the East London parish, where Witham business owner Mr McCarthy was born and grew up, on Saturday, October 13.

Mrs Chambers said: "He was born in Bethnal Green in 1954 and moved to Witham in the 70s so we are walking through his life.

"In his later years he spent most of the time in Thailand and would come back to Witham for a couple of months a year.

"We wanted the walk to symbolise us travelling through his life, obviously cutting out the Thailand part."

The journey is around 40 miles, and is set to take the siblings most of a whole day to complete.

But despite the mammoth effort, the duo are excited to hopefully help save lives in the future.

"It is about forty miles. We have been training hard for it and we are doing it all in one walk," Mrs Chambers said.

"We are both looking forward to it.

"We have set a target of £1,000 to raise and we are up to £400 at the moment.

"Dad was quite well known in some of the pubs around Witham so we are hoping we can raise a bit more cash by collecting in them."
