Sandra Harvey, 68, from Talgarth (pictured front), suffered a fall while out riding last month, after her horse was startled by a quad on a quiet country lane near her home.
Although she was wearing a riding hat, Sandra suffered serious head injuries and died at the University Hospital of Wales, Cardiff, 11 days later. After her death her organs were used to transformed the lives of five people.
Since her death riders from all over Britain have been inspired to become organ donors thanks to an awareness campaign on Facebook.
Friend and campaigner Liz Rose said: "Sandra felt so strongly about helping others after her death and its given comfort to her family and friends.
"We were shocked to find out from doctors how few people are on the donor register and how many people's lives could be saved by that one act.
"We know that Sandra would have been overjoyed that so many people have already signed up to the campaign, it's an incredible tribute to an amazing woman."
Sandra, a retired headmistress, had been joint-master of the Brecon and Talybont Hunt for eight years.
Liz said: "The donation of her liver, kidneys and corneas has transformed the lives of five people and their families. We can't bring her back, but now she will live on through this final act of generosity."
NHS statistics show that three people a day die before they can have a transplant because there are not enough organs available. And only 27 per cent of people have joined the NHS Organ Donor Register.
Members of Facebook can join the campaign by typing in "Become an organ donor in memory of Sandra".
