A young woman who collapsed during the London Marathon died because of acute cardiac failure complicated by a now-banned drug, a coroner has ruled.
Claire Squires, aged 30, fell to the ground near the finishing line in April last year. She had taken a supplement containing DMAA, which at the time was legal.
Her boyfriend Simon Van Herrewege, speaking outside Southwark Crown Court, said Claire would never have taken anything she knew would harm her.
