This was good as RDA tried to encourage their riders to take parts in outside events, Ms Holmes said.
"It's what other riders do, its giving our riders a chance to do what other riders do."
Acting Hastings Mayor Sandra Hazlehurst said it had been a privilege to present ribbons to young riders.
"To see the bond the children had with the horses was absolute magic," she said.
"Riding for the disable make an enormous difference to the lives of the children involved, and we're so lucky to have the community volunteers who support this incredible organisation, and bring the magic into the children's lives."
At a team event each child received a ribbon for participating. They were each also awarded a ribbon which acknowledged what skills they had done best at.
"We also have a shield that we give to the winning team, but we [Hastings] retained it thank goodness", Ms Holmes said.
Ms Holmes said the event had been in the pipeline for several months, and would not have been possible without the "shed load of volunteers" who gave up their time to make it happen.
RDA caters for people of all ages, who are often physically challenged with cerebral palsy, spina bifida, paraplegia, multiple sclerosis, muscular dystrophy, traumatic brain injury, stroke or have visual or hearing impairment, have intellectual disabilities or multiple disabilities or have learning disabilities.
Riding develops, improves and promotes balance and co-ordination, posture and muscle tone, concentration, self-discipline and self-esteem, perception and spatial awareness, communication and social skills, independence and encourages decision-making.
