A charity campaigner is to undertake a gruelling 45-mile challenge, to raise awareness and funding to tackle the disease that killed her daughter.

Amanda Walker and her partner Ray Mifsud have spent the past year raising over £81,000 in memory of their daughter Abbie Mifsud, who died from a rare, incurable and inoperable form of brain tumour called diffuse intrinsic pontine glioma (DIPG) in September 2011.

The Mums Against DIPG (MAD) Lakes Challenge will see Amanda joined by a team of 20 other women, including two other mothers who have lost their daughters to DIPG.

The intrepid group will attempt to canoe around 20 miles, cycle over 13 miles and mountaineer over 10 miles – including an abseil down a 60ft cliff – all in the space of 24 hours on May 25 and 26 this year. They are hoping to bring in a whopping £100,000 through their efforts.

Amanda (pictured left, with Ray) said: “After what we’ve been through with our daughters, we’re convinced this is going to be a breeze.

“Our girls were absolute heroes, and so brave in facing what they went through.

“If they could do that, then we’re determined that we can do this, and they will be right there with us to keep us going.

“There’s a lot of work to be done between now and then, and we’re all just trying to build up our strength and stamina, but my biggest worry is staying awake for that long!

“We’ve set ourselves a massive fundraising target, but between the 20 of us, I’m sure we can do it.

“If there are any businesses or organisations who can support us, we’d love to hear from them.”

To launch the event a video has been released, to coincide with what would have been Abbie’s eighth birthday.
