Crawley caretaker boss Ben Judge has urged his tired players to make one last push for survival.
Judge says Reds are "dead on their feet" following a season battling relegation and playing two games in three days over Easter.
They can as good as guarantee their status in the Conference with a win at Northwich Victoria tomorrow.
And Judge wants his side to dig deep into their energy reserves to drag themselves past the safety post.
He said: "A lot of the boys are absolutely shattered. You can see in training that the ones who have played 30-40 games are almost dead on their feet.
"But we need to make one last effort and put it in for another 90 minutes and then hopefully we can relax a bit.
"I think one more win will do it, so this is a massive game. If we get the three points we should be okay but if we don't we will be looking over our shoulders again.
"We are desperate to get it over with so we can enjoy the other three games.
We don't want to be going to places like Halifax having to get a result, so we will treat this game like a cup final."
Judge admits he and fellow jointbosses Dave Woozley and John Yems have also been feeling the strain of the relegation dogfight and is disappointed Reds have left it so late to secure safety.
He said: "It has been non-stop. You find yourself cheering on other teams and looking at Teletext cheering the goals as they go in.
"It is a ridiculous scenario really. I think we should have been out of it a few weeks ago. We had three draws in a row which was not a good run to go on but hopefully now we have done enough to get out of it."
Northwich effectively sealed their future in nonleague's top flight with a 2-0 win over newly crowned champions Dagenham on Wednesday.
It took them up to 12th, eight points clear of the trap door, pushing Reds down to 15th in the process.
Judge says the fact Victoria are already safe may not work in Crawley's favour.
He said: "Maybe they will take their eye off the ball now they are okay but it could work the other way.
"They could go out and enjoy themselves now the pressure is off. People are sometimes scared to express themselves when there is a lot at stake. Once we are safe, you will probably see better performances from us."
Reds have almost a full squad to choose from following striker Lloyd Blackman's return after five weeks on the sidelines with a groin injury.
Blackman is back quicker than expected after having a week of rehabilitation at Lilleshall.
The only doubt is left-back Ronnie Bull after he missed training yesterday with 'flu.
Judge will make his first start since January if Bull does not recover in time.
The Conference will be known as The Blue Square premier division from next season after the league agreed a new sponsorship.
Conference south will be called the Blue Square Southern division.
