A number of Irish Defence Forces Veterans have set off on a 170km trek from Co. Roscommon to Dublin City.
It's part of a fundraising effort for the charity, 'ONE,' which supports ex-service personnel.
The veterans have been marching along the Irish Famine Trail, which dates back to 1847 and cuts through the Shannonside region.
Taking place over seven days, the veterans have been marching from Strokestown since this morning.
Jimmy Fullam is an ex-member of the Defence Forces.
As he walked the first leg to Clondra, he spoke on the Joe Finnegan Show and explained that it is vital to support veterans' mental health:
