The charity fund raising page for Claire Squires, who collapsed and died during the London Marathon last weekend has now reached £1m.
She was raising money for the Samaritans, who her mother Cilla had volunteered with for more than 20 years.
Miss Squires, 30, will be buried on Wednesday at St Andrew's Church in the village of North Kilworth, Leicestershire next to her brother Grant, who died in 2001 aged 25.
Donations made in memory of 30-year-old Claire Squires have broken the £1million mark on the same day her funeral has been announced.
The 30-year-old who died during Sunday's London Marathon has been called an "inspiration" and "incredible".
Donations to the charity of Claire Squires, the young woman who died in the London marathon, have reached almost £220,000.
