MacCarthy was injured in a rotational fall seven years ago
Warwickshire Paralympic hopeful Ruth MacCarthy has stepped up her bid to find a horse ahead of the 2012 Games.
MacCarthy hopes to compete in dressage but her usual ride is injured.
"We're looking at an advanced medium-level horse to go in there straight away and be able to compete," she told BBC Coventry & Warwickshire.
"It doesn't have to have had any experience with the Paralympics before but it does have to have a proven track record in able-bodied dressage.
The 26-year-old from Wellesbourne had a riding accident when she was 19.
MacCarthy broke her back and hip and suffered a crushed pelvis as well as tissue and nerve damage when the horse she was riding fell on top of her.
With selectors set to monitor potential competitors from this June, the Warwickshire rider knows she needs to find a new ride soon.
MacCarthy added: "I'm really looking for a horse by the end of April so that I can have a bit of time working with it.
"I train with Lee Pearson and Maria Eilberg and they are essential in making sure that the transition to the horse happens smoothly and that we can get moving forward."
