Two brothers taking part in a marathon challenge for dementia research are set to smash a £1m (€1.14m) fundraising target as they travel across Ireland.

Jordan and Cian Adams have been diagnosed with a rare gene which causes frontotemporal dementia (FTD), which means they have a high chance of developing dementia in their 40s.
