A female competitor at the weekend events held at the popular Fieldstone Summer Showcase on Plymouth Street was transported by medical helicopter after a fall from her horse.
Halifax police and fire were on a detail for the event and were able to quickly tend to the young woman.
A paramedic and EMT rendered first aid as the ambulance arrived with staff quickly transporting her to a Medflight, which flew her to Boston, according to Fire Chief Jason Viveiros.
The horse had landed on the competitor who was only identified as a 29-year old participant from out -of- state. She reportedly needed surgical intervention following the incident for what were termed as serious injuries.
