Why have teams fallen short in Six Nations three-peat bid?

England, Wales and Ireland have all previously fallen short in their bid for three titles in a row

Ireland head into the 2025 Six Nations looking to go where no team has ever been before.

A hat-trick of titles has never been achieved in the men's game, and Ireland are five games away from writing their names in the history books.

If you think back to England's World Cup winners, France's mid-2000s domination or Warren Gatland's golden era with Wales, it's almost a surprise that it's not been achieved before.

It last happened when France's name appeared on the trophy on four consecutive occasions in the Five Nations in the late 1980s.

But even then, their 1986 and '88 titles were shared with Scotland and Wales.

Ireland will look to avoid a similar fate to those who have come close before, but where have teams fallen short in the past?

2018 - England fall apart in defence

England's defeat at Murrayfield kickstarted a run of three straight losses

England were the last team to go for three titles in a row after winning the Six Nations in 2017 and 2018, but their bid to make it a hat-trick was something of a disaster.

Eddie Jones' side made a good start with a big win over Italy in Rome, and that was followed by an edgy win at home over Wales.

So far, so good. But things would soon start to unravel.

Scotland stunned England to claim the Calcutta Cup for the first time since 2008 with their 25-13 win the largest victory for the Scots over their rivals in the Six Nations.

Next up, England fell in Paris as the French ran out convincing 22-16 winners.

Their chance for the title was over, but could they stop Joe Schmidt's Irish juggernaut from clinching the Grand Slam at Twickenham on St Patrick's Day?

Ultimately, Ireland were too strong and ended their campaign with a perfect record as England finished fifth in the table with two wins for their efforts.

2016 - England perfect as Ireland stumble

Ireland's bid for three Six Nations in a row ended at Twickenham

After ending Wales' run of titles in 2014, it was Ireland's turn to win back-to-back Six Nations the following year and eyes soon turned to a potential hat-trick.

France and England won their first matches before, in a Six Nations rarity, Ireland and Wales drew their opener 16-all.

The Irish title defence took a further blow as France ran out 10-9 winners in Paris, and England scored 15 unanswered points in the second half to end Ireland's hopes of retaining the title.

Ireland finally collected their first win against Italy, and England's biggest scare of the tournament came as they held off a ferocious Welsh fightback to win 25-21.

Having missed out on points difference the previous year, England were so good that their title was secured with a game to spare as France lost in Scotland.

Eddie Jones' side wrapped up a first Grand Slam since 2003 with a win over France. Job done.

2014 - Wales golden era ends

Wales fell just short of three titles in a row in one of the Six Nations' most competitive years

After winning the Grand Slam in 2012 and another title the following year, Wales fell just two points short of making three Six Nations titles in a row in 2014.

Wales and Ireland both won their opening matches, while Gael Fickou's last-gasp try saw France defeat England in a thriller.

Ireland blew holders Wales away in Dublin in round two, while England and France collected big wins.

The championship took a big twist in the third round as Wales bounced back to defeat France, while England edged past Ireland at Twickenham.

It looked like it was anyone's title, but Wales' hopes were ended by England, as Ireland and France both won again.

Going into the final day, Ireland, France and England could all still claim the title.

England hammered Italy to pile the pressure on Ireland in Paris. Johnny Sexton's 17 points helped Ireland over the line by two points, despite a late French fightback.

It was one of the most competitive years in Six Nations history, and it was Ireland who prevailed.

2008 - Wales Grand Slam stops France run

Wales won a famous Grand Slam in 2008 to stop France winning three titles in a row

After finishing fifth with one victory the previous year, Wales' Grand Slam in 2008 is one of the most famous titles in the championship's storied history, which also denied France three in a row.

Grand Slams are often built on special moments, and two converted tries in the space of the three minutes, courtesy of Lee Byrne, Mike Phillips and the boot of James Hook, handed Wales victory over England at Twickenham for the first time in 20 years.

Scotland were the next to fall to Warren Gatland's side, while Italy were also put to the sword in Cardiff. In the third round of fixtures France, who were going for a third title in a row, lost to England in Paris - which opened the door for Welsh history.

Shane Williams scored his 40th try for Wales as Gatland's side held on for a 16-12 win over Ireland in Dublin, while Welsh title hopes were boosted by Scotland's win over England.

France required a big win over Wales to have any hope of retaining their title, but the Welsh had too much in Cardiff and sealed a famous success.

It was a year you had to be perfect to stop Wales, who conceded a remarkable two tries all tournament.

2002 - France halt England dominance

England won three of the first four Six Nations at the start of the millenium

England were the dominant force in the Six Nations at the start of the millennium with three of the first four titles.

However, Clive Woodward's side fell short of a three-peat at the hands of France in 2002 - who achieved the first Grand Slam of the Six Nations era.

Going into the tournament as favourites, England hammered Scotland and put a big score on Ireland to get their campaign off to a perfect start.

France, meanwhile, had defeated Italy and held off a late Wales rally in Cardiff.

The decisive turn came in Paris when England were unable to overturn a 17-7 half-time deficit despite a late fightback by the holders.

While England hammered Wales and Italy in their final two matches, a nervy victory over Scotland and a big win over Ireland secured the Grand Slam for Les Bleus.

However, it didn't work out too badly in the long run. England retained the Six Nations with a Grand Slam 12 months later, and their historic 2003 was capped off with their famous World Cup win over Australia.
