The FTD brothers are running in Co. Cavan this morning.
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.
Their mother Geraldine died at the age of 52 after developing FTD.
They are running 32 marathons in 32 days, and today's run in Cavan is the 10th marathon.
People are being encouraged to show their appreciation for the great work the lads have been doing and come out and support the lads outside Cavan bus station.
