Two brothers have completed 32 marathons in 32 days across Ireland – one in each county – in aid of dementia research.Jordan and Cian Adams crossed the finish line in Merrion Square, Dublin, to a roaring crowd and chants of “ole ole ole”.The brothers, who are from Redditch, England, with Irish connections from Longford and Leitrim, started the challenge in Co Antrim on April 27th – a day after Jordan completed the London Marathon with a 25kg fridge on his back. This made it 33 marathons in 33 days for the 31-year-old.The brothers carry a rare gene for frontotemporal dementia (FTD) and have a 99.9 per cent chance that they will both develop the aggressive terminal illness in the 40s.The brothers approach the finish line in Merrion Square.

There’s people in places not too far from here that can and we’re going to go and make sure we have those conversations,” Jordan said.“It’s money that moves the needle.”His brother Cian (25) spoke of some challenges along the route. Jordan’s birthday coincided with their Co Wicklow marathon, which included a 487m climb that caused a “few harsh words said”.

Cian said running has helped him and his brother cope with their grief.During a speech after the marathon, Jordan noted how difficult it was to watch his mother be “completely stripped of everything that made her the amazing human being she was”, adding how proud she would be of the accomplishment her family has made.Jordan and Cian’s father, Glen Adams shared this pride in his boys but said “if I was Irish, I’d be very proud”.“Ireland has done itself very proud on the support of my family,” Glen said.Glen described his role in the campaign as a “pack mule”, adding that “if something needs carrying, I carry it”. In the mornings before each marathon, Glen loaded up their truck with everything needed for the day ahead whether it be orange juice or shaving cream. The brothers in Merrion Square on Thursday.
