Sophie Fouracre, aged 34, was fatally injured in a cross-country accident riding Rhubarbsfox Brittania, at Swalcliffe Park, Oxfordshire, England.
 
Hours later at Penrith in Cumbria, Kerry Donoghue, aged 42, died following a cross-country accident riding Carneyhaugh Rua.
 
At both venues, the event medical teams responded immediately and provided emergency treatment. Despite their best efforts sadly neither rider could be saved.
 
Both horses were examined by the attending veterinary team and were found to be uninjured.
 
Rosie Williams, Chief Executive of British Eventing, said: "The British Eventing community is heartbroken. On behalf of everyone at British Eventing, I want to extend our deepest condolences to Kerry and Sophie's families, friends and loved ones at this devastating time. Our thoughts are also with their fellow competitors, organisers, officials, volunteers and everyone who has been affected by these tragic events.
 
"We are immensely grateful to the organisers, doctors, paramedics, veterinary teams, officials and emergency services at both events for the professionalism, compassion and care they showed in the most difficult of circumstances.
 
"The loss of two members of our eventing family on the same day is almost beyond words, and we know the sadness of these events will be felt profoundly across the sport for some time to come."
 
In accordance with British Eventing's safety and incident review procedures, comprehensive reviews of both accidents will now be undertaken. 
 
We recognise the impact these tragic events will have across the eventing community. Anyone affected is encouraged to seek support through the British Eventing Support Trust Helpline, which is available 24 hours a day, seven days a week, on07780 008877.
