When Rochdale face York City in their National League final-day decider on Saturday, the result will decide who wins the title - but will also have a potentially enormous impact on both clubs' respective futures.

Over 45 matchdays, the two teams have far outclassed the rest of their rivals in the fifth tier of English football, going toe-to-toe in an epic race where dropped points have been extremely rare.

Now only one game remains.

Leaders York are two points ahead, having amassed a whopping 107, but Rochdale have home advantage and their 10,249-capacity Crown Oil Arena has long been sold out for the match (12:30 BST kick-off).

Rochdale were almost down and out last weekend, but scored a 99th-minute winner away at Braintree to keep their title charge alive and deject York, whose players were watching a live stream on the pitch after they beat Yeovil.

Never before have two teams with so many points faced off in a winner-takes-all final-day decider for a place in the English Football League.

The champions will take home the trophy and be promoted to League Two, while the runners-up will need to dust themselves off and battle through the gruelling six-team play-offs.

The National League title race is so fraught with danger because the winners tend to enjoy a positive long-term future, while the runners-up often face lasting negative consequences.

Let's start with the bad news.

Since the play-off system and its second promotion spot were introduced to the National League at the end of the 2002-03 season, the team finishing second has been promoted only six times out of 23.

During that time, there have been a fair few horror stories involving high-flying runners-up who missed out on the title by small margins then losing in the play-offs to sides who finished way below them.

In 2003-04, Hereford finished second with 17 more points than third-placed Shrewsbury, who were promoted via the play-offs instead. Hereford then finished second and missed out in the play-offs again the following year, before finally being promoted from second place, at the third time of asking, in 2005-06.

Now playing in the Championship, Wrexham endured a torrid time after finishing second on 98 points in 2011-12. They were immediately knocked out of the play-off semi-finals, and were mired in mid-table mediocrity in the National League for more than a decade before finally being promoted as champions in 2022-23.

York themselves have been here before. They were terrific last season too, earning 96 points but finishing five behind Barnet, before being knocked out of the play-offs in the semi-finals by Oldham, who had finished 26 points behind them in fifth.

While the psychology of narrowly missing out on promotion is a huge obstacle for National League runners-up, the high turnover of players every year in the fifth tier makes it hard for squads who have just come up short to build momentum in the following season - meaning a single missed promotion chance can lead to years in the doldrums.

But for the winners, the signs are hugely promising.

Since the 2002-03 revamp, not a single team promoted from the National League to League Two has been relegated straight back down the following season.

In fact, of the 43 different clubs promoted in that time, only 16 have dropped back into the National League at all in the subsequent seasons.

And never mind regression, most clubs have actually progressed further up the pyramid.

Of those 43, 24 have played at least a single season in League One, six have gone as high as the Championship and one (Luton) has even played in the Premier League.

For the National League champions, then, promotion to the EFL often leads to a huge boon, while the runners-up more likely than not find themselves trapped in the fifth tier for a while longer.

Despite the stunning campaigns both York and Rochdale have put together, they have not quite managed to become the most impressive top two in National League history.

The combined 212 points they have earned this season (with a potential total of three more to come if one side wins on Saturday) is slightly below the 218 accrued by champions Wrexham and runners-up Notts County in 2022-23.

That season, Wrexham won the title with 111 points and a game to spare, while Notts County were promoted by the skin of their teeth in the play-offs after winning on penalties at Wembley against Chesterfield, who had finished a whopping 23 points behind them in third.

"The psychological side of bringing yourself back up to compete in massive games after not quite reaching your goal is very challenging," says Sam Slocombe, who spent six seasons as Notts County's goalkeeper before becoming a coach at the club last summer.

"You have to verbalise it and say to each other 'we wanted to get promoted and we're still in an unbelievable position to do that'. That burning desire needs to stay there.

"National League play-offs are one-legged, pure tournament football - what you did week in, week out doesn't matter any more.

"If you finish second, you also have a gap where the teams lower down play the first play-off match. I found that very challenging because they get to keep their intensity while you're waiting around - maybe your level is dropping.

"The lower play-off teams will go to York or Rochdale with zero pressure - it's a freebie for them."

Notts County finished their first season in League Two in mid-table, before losing in the play-off semi-finals last season, and are in promotion contention again this year.

"Winning week in, week out, in the National League means the feeling in the group is really positive. You go on to the pitch thinking 'we'll turn up, we'll play our stuff, and we'll win'.

"Once you go up, you can take that morale, the feeling in the crowd, and confidence in your way of playing into the next season, which makes it a hard place for the established League Two teams to come and play."

In 2025 the National League launched its 3UP campaign, which aims to secure a third promotion spot for National League clubs into League Two.

The campaign is supported by all 72 clubs in the National League and the North and South divisions below it, as well as the Football Supporters' Association.

Those behind the campaign believe another title race contested by two teams capable of putting up a tally of more than 100 points, as well as the long-standing success enjoyed by clubs after promotion to the EFL, strengthens their argument.

Any change to the promotion quota would require a majority of EFL clubs to vote in favour of a change to the system's rules.

"I agree with the argument, because I've been through it, and if ours and Wrexham's legacy helps them get it then great," Slocombe says.

"But I really don't think there will be a rule change. If you're an owner in the Football League, why would you vote for something that increases your chances of being relegated?

"The people who would make the decision have nothing to gain and everything to lose."
