After running every mountain in Ireland last year, endurance athlete Seán is back with an even bigger challenge, this time he's taking on the entire Wild Atlantic Way on foot.

He set off this morning with the goal of running the full 2,500km coastal route in just 27 days, that’s over 100 kilometres a day.

He’ll be passing through Clare, including the Cliffs of Moher, in the days ahead — and you can follow his journey on Instagram at @runseanierun.

To find out more about the run and how it's going so far, Derrick Lynch was joined by ultra runner, Sean Clifford.
