This year's series of Ireland’s Fittest Family series return sees the toughest families in the country take on the most gruelling and physical challenges imaginable. It will be filmed over the course of three weeks in our new hub at Hell & Back in Kilruddery, Co. Wicklow. Set across acres of land at the foothills of the Wicklow mountains this is the perfect location to put our families through their paces.

There are four levels that families must compete to win the title. Starting in The Forest over four weeks, 16 families will become eight as each week two families will be eliminated. 

The eight families that survive The Forest will progress to the quarter-finals in the lake and will be put to the test in the water. 

Only six families will do enough to stay in the game and make it to the semi-final in the swamp. 

The best four families will make it through to the final and these families will be pushed to new heights on the mountain

One family will reach the summit and be crowned Ireland’s Fittest Family winner.

Sundays, 6.30pm, RTÉ One.
