A young woman who died in the London Marathon was using a caffeine-like supplement she bought online, an inquest has heard today.
Claire Squires, 30, from Great Bowden, near Market Harborough, collapsed and died a mile from the finish line last April.
She had bought a supplement called Jack3D containing a substance called DMAA, which increases the heart rate, Southwark Coroner's Court, in London, was told. Her boyfriend, Simon Van Herrewege, told the hearing Claire put the supplement, which was "like strong caffeine", in her water bottle during the marathon.
Pathologist Dr John Van der Walt, who conducted the post mortem examination, concluded that "acute cardiac failure due to extreme physical exertion complicated by the presence of DMAA was the cause of death". Claire, a hairdresser, aimed to raise £500 for Samaritans but the total surged to more than £1.1m on news of her death.
She was one of 80 people running in support of the charity and had been a keen fundraiser for Samaritans in support of her mother, Cilla, who has been a volunteer with the organisation for the past 24 years.
The charity has since worked with Miss Squires' mother to develop The Claire Squires Fund - a programme of projects that reflect how she would have wanted the money to be used.
Friends and relatives have also set up the Squires Effect charity to aid people who need help.
The inquest continues.
