Ms Sedgwick completed the distance from Battersea Park to Boscombe in five days to meet her grandad, Ivor, at his favourite spot on the beach. The 85-year-old, who was diagnosed with dementia in 2023, used to be a running coach but his worsening condition means he now lives in a care home with his wife, Janet. Ms Sedgwick, 28, started her challenge on 2 October, running nearly seven hours each day to raise money for the Alzheimer's Society.
