An inquest is to be held today into the death of Claire Squires, from Great Bowden, Leicestershire.
The 30-year-old hairdresser collapsed near the finish line of the London Marathon last year.
She aimed to raise £500 for Samaritans but the total jumped to more than £1 million following a public outpouring of support in the aftermath of her death.
The inquest will be held at Southwark Coroner's Court in London.
