They're running marathons, shaving their heads and doing hundreds of press-ups. They're holding socially distanced bingo and online quizzes. People all over the country are embracing virtual and solo challenges to raise money for charity.
At his home in Shankill, Co Dublin, Barry Jones is gearing up to walk or run 100km in June for the LauraLynn Children's Hospice.
His nine-year-old daughter Molly has been receiving respite care at LauraLynn for the past five years. Living with a rare chromosome disorder, she has many medical issues and the hospice's services provide a lifeline for Barry and his wife Mairead, who have two younger daughters, Cara (6) and Elsie (5).
Barry, who works with adults with intellectual disabilities, regularly fundraises for the charity. He just completed a 3,000 press-ups challenge for the hospice last month, raising €3,000.
Mark Mooney is hoping for a reboot of the ice bucket challenge that soaked the world four years ago. The nine-year-old from Walterstown, Co Meath, did his own ice bucket challenge and wants more people to follow suit to raise money for the Irish Cancer Society. All his efforts are in honour of his father, John, who was diagnosed with colorectal cancer in January and is undergoing treatment.
Mark's mum Naomi Connell says he has raised €5,000 so far. With so much stress and disappointment in her son's life, she says, Mark wanted to do something positive.
Eugene O'Leary (77), from Howth, Co Dublin, is over halfway through his 10km a day for May. Every day he leaves his home and walks to Baldoyle or Kilbarrack and back, tracking and posting his progress online for his social media followers.
Over the course of the past two decades, the father-of-seven, has raised more than €100,000 for Children's Health Ireland at Crumlin. The hospital holds a special place in his heart. When his second youngest daughter, Helen, was born, she spent a long time in the care of doctors and nurses at the hospital as she had heart treatment. She died in 2002 at the age of 19 but her father never forgot the care she received. He has raised €5,550 so far with his 10km challenge.
In Dublin, wedding photographer Katie Kavanagh took pictures of her neighbours and residents of Dublin 8 on their doorsteps. Her subjects donated money to Purple House Cancer Support in return for copies of the 'doortraits'.
