Alan Morrissey was joined by four teenagers who have taken on an almighty challenge, all for a good cause.

16 year-old Keane Marquardt, and Seán Judson, Finn Craig and Seán Durcan, all aged 17, are heading from one end of Ireland to raise funds for the Irish Cancer Society.

The four lads are travelling from Mizen Head to Malin Head, the southernmost to the northernmost point in Ireland, with a journey through Clare along the way.

What makes their epic trek even more difficult, is that they are doing it on foot!
