Sundays are about to get a little less dynamic as Ireland's Fittest Family comes to an end this weekend, with four families facing off in the cathedral of Irish sport, Croke Park in Dublin. Don't fret, though: in a season that saw multiple records smashed, expectations obliterated and some of the closest finishes we've ever seen, it goes without saying that Sunday's final will be some of the most exciting television all year. 

Taking place in the iconic stadium for the first time, there will be a poetic symmetry to the four teams facing off in the very place they watched their sporting heroes play, coached by some of those very heroes. Expect tears, of the happy and sad varieties, hugs and buckets of inspiring wisdom.

A place in the final is hard-won, but nothing could prepare them for the challenges on offer once they arrive there. A medley of punishing tasks will push them in ways never before seen on the show, such as Sheer Scaleform from Cusack Stand, a hair-raising variation on Hanging Tough and a final epic race along the iconic pitch, which ends with ramps at Hill 16. 

The Lawlors from Limerick will be guided by coach Donncha O’Callaghan, who wants them to win more than anything and will be chasing a goal of his own - his second title in just two years on the show.  

The McDonalds from Laois are led by coach Davy Fitzgerald, who delights in finals day in this stadium. After a triumphant week last week, he'll be bringing more ferocity and determination as he drives the McDonald's forward. 

Anna Geary comes into the final with two families, leaving her in an undoubtedly tricky position, encouraging two competing families. The Finnegan Hogans from Cork and the Coneys from Tyrone will face off under Anna's guidance, and with twice the chance to win she will be driven and giving everything to both her families.

Ahead of the tense final, let's look back at the families who have fought their way through mud, fire and the limits of willpower to bring it home in the cathedral of Irish sport. 

The Lawlors

The Lawlors from Limerick, as fond hunters, adapted quickly to navigating the messy and back-breaking obstacles of the great outdoors, with mother Dympna (46) and sons Jonah (26), Matthew (22) and Darren (21) consistently working as a unit and wowing viewers - and themselves - with their strength. 

In the notorious Hanging Tough challenge, for instance, Dympna overcame her fear of water to put in a brilliant performance, staying on the bar for the longest amount of time out of her team and leading them to securing a place in the finals. 

The McDonalds

Hailing from Laois, the McDonalds came into the competition with the medals to prove their sporting excellence. Led by father Martin (61), the team - including daughters Breda (25) and Kate (23) and son Cian (17) - was another shining example of peak fitness at any age. 

It was Martin who smashed the first record of the season, when during the Hanging Tough challenge he stayed on the bar for an incredible 5:50 minutes, giving his team the best finishing time of the episode. 

In the semifinals, they overcame difficulties in the Swamp Trek and anxieties over being the only team with two female teammates to secure a place in the final, confirming them as fierce competition. 

The Finnegan Hogans 

Featuring the oldest competitor the show has ever seen, the Finnegan Hogans came into the competition with much focus placed on them and rather than baulk under that pressure, they have emerged as one of the most unexpected and fierce teams on the show. 

Grandfather Martin (63) has led son Paul (41), daughter-in-law Louise (36) and grandson Dylan (17) through each challenge, using their experience as tug-of-war champions to sail through the fire truck pull. Although a few stumbles and an injured ankle for Louise hindered their performance somewhat in the semifinals, they are a shining example of why you shouldn't judge a book by its cover. 

The Coneys 

As the first family from Tyrone to feature on the show, the Coneys are also the oldest family on the show, proving that age means little when you're exceptionally fit.

Mother Colette (59) and sons Shane (39), Gary (37) and Paul (28) put in consistently impressive performances, with Colette, in particular, showing extreme strength in Hanging Tough and shattering expectations left, right and centre. 

It hasn't all been plain sailing for the team, however: following a brutal run through the Swamp Trek challenge during the first semifinal at Kilruddery Estate, Gary was diagnosed with hypothermia, ruling him out of the following challenge. Later that episode, though, they secured a place in the final by pulling together and communicating. 

Don't miss all the action this Sunday 9th December, 6.30pm on RTÉ One.
