Riders started their challenge at about 12.30pm and finally finished at about 3pm having completed 100 laps of the Cannock equestrian yard run by Laura Wells.
They managed to raise a total of £468 through a JustGiving page and plan to donate half of the funds to the Captain Sir Tom Moore charity and half to the mental health charity, MIND.
The Captain Sir Tom Moore 100 challenge was started by his family to mark what would have been his 101st birthday.
Mother-of-two Laura, aged 40, who runs LAW Equestrian and rents the yard from Jacquie Halford, said: "We decided to take part in the 100-challenge in memory of Captain Sir Tom Moore and invited staff and clients to come along dressed as superheroes or National Health staff and the fancy dress outfits were fantastic.
"Both children and adults took part and it really was a fun day.
"People really entered into the spirit of the event and dressed the part.
"It really was beyond our expectations and the outfits were really amazing.
"I have red hair and dressed as Poison Ivy and my daughter, Ella Freeman, aged seven, dressed as the Wasp from The Avengers film, and my son, Liam Freeman, aged 13, as a doctor.
"In all there were 25 people taking part in the challenge.
"We decided to share the money raised with MIND as we felt that people with mental health issues and learning disabilities, as well as children get a lot from being around horses.
"Fortunately the weather was good and we raised a total of £468 which will be split between the two charities."
