A father and daughter have completed a gruelling challenge to raise money for curing brain cancer after a friend died.

Alice Whale from Bristol and her dad Spud from Greenwich swam 10k after they were motivated by the loss of Glenn McMahon, who died in 2015, two years after his diagnosis.

Glenn, who was from Mottingham, was diagnosed with a glioblastoma, an aggressive type of brain tumour, after suffering from co-ordination problems.

He underwent radiotherapy and chemotherapy but passed away aged 53, leaving his wife Wendy.

Wendy has worked tirelessly to increase awareness of brain tumours and set up a fundraising group, the Glenn McMahon Foundation.

Alice, a content manager, and Spud, a 54-year-old co-ordinator for EDF Energy, swam along the River Dart from Totnes to Dittisham, and raised over £700 for the Brain Tumour Research charity.

Alice said: “Dad and I both felt quite nervous about the swim but we were proud to raise money for this vital cause.

“We were glad to have crossed the finish line before the tide came in and had a great time on the day.

“Glenn was an awesome guy and a close friend of the Whale family. We are proud to help Wendy on her mission and raise as much as possible for Brain Tumour Research.”

Brain tumours are indiscriminate; they can affect anyone at any age.

What’s more, they kill more children and adults under the age of 40 than any other cancer, yet just one per cent of the national spend on cancer research has been allocated to this devastating disease.
