This is the terrifying moment the horse of 10-year-old rider bolted sending her speeding down a track at 28mph.

Michelle Ross, 48, was out on a hack with her horse Leila, 12, and a couple of friends when the incident unfolded.

The group included a young girl riding Loki, a horse Michelle was familiar with, having ridden with his previous owner on hunts and trail rides.

The plan was for the girl to ride calmly next to Michelle but Loki had other ideas and suddenly took off.

Michelle, from Blidworth, Nottinghamshire, said "He just decided to go for a run, which was quite naughty."

"He was excited because he recognized the field and although he was well-behaved in the woods, he just wanted to run."

Michelle, despite feeling internally petrified, kept her composure and guided the young rider to stay calm and slowly regain control of the runaway horse.

Michelle said: "It's a scary situation but I didn't want the girl to be any more frightened than she already was."

The young rider, protected by her gear, held on and followed Michelle's instructions, eventually slowing Loki down.

Despite the shock, the ride ended with smiles and relief.

Michelle said: "Nothing bad happened and she did so well."

"It was an ecstatic moment by the end."
