Falls are a risk that horse riders accept from a young age, but after two riders died in recent competitions and one was seriously injured, the safety of the sport is once again under scrutiny.
Eventer Laura Collett was in a coma for six days after falling off her horse in July.
Paramedics say she only survived thanks to a piece of equipment called an "air jacket".
