Glen's story over the last four years has been one of continual, steady progression and now they're one step away from the ultimate.
It's just under a fortnight ago since they beat Kilmacud Crokes in the fog of Newry, avenging last year's controversial All-Ireland decider and booking a final date with St Brigid's this weekend.
The re-match with Kilmacud - almost 12 months after the CCCC had initially ordered a replay of their 2022-23 All-Ireland final - was hotly anticipated by neutrals everywhere, though it's questionable how many people got to "see" the game, either at the venue or on TV, given the extraordinarily dense fog that hung around the ground.
After the game, Glen captain Michael Warnock admitted that he and direct opponent Shane Walsh lost track of where the ball was on the pitch at one stage and comparisons were drawn with the Republic of Ireland's away play-off tie in Bosnia in November 2015, when the RTÉ commentary took a moment to realise that Robbie Brady had scored a goal.
While Kilmacud manager Robbie Brennan lambasted the decision to play the game in the conditions, Glass broadly backs up the referee's call. Though he does admit things got significantly more difficult in the second half, which contributed to the chaotic finale to the game.
"It got worse in the second half. The first half was actually fine, you could see better on the pitch than what the media and [people in the] stand could see," the Derry midfielder told RTÉ Sport.
"So, there was no problem in terms of the game going ahead. Conor Lane probably made the right decision.
"But the second half slowly got worse. When you're under pressure in a high performance area, not having full visibility plays a part in it.
"There might be kick-pass on to a player 60 metres up the pitch to release a bit of pressure - but you couldn't play the pass because you didn't know if it was a Crokes player, a Glen player or the referee or the umpire.
"It was the same for Crokes and we were just lucky to scrape past [them] with a one-point win."
Notwithstanding the worsening fog, Glass never had any worry the game might be abandoned with Glen in the box-seat.
"When you're in that environment, you're just on high alert the whole time so concentration probably wasn't an issue.
"And the thought of Conor Lane blowing up the whistle didn't come into our heads at all. We could only focus on what we could control and that was our performance in the second half
And anyway, he notes, "there probably wasn't enough room in the schedule to fit in another game if it had to come to that."

On the pitch immediately after their Ulster final win, Glass told Marty Morrissey that the prospect of facing Kilmacud again had loomed large on his mind all year - "I'd be lying and playing it down [saying] that I didn't think that".
But after the semi-final win, he says they were conscious of keeping any euphoria in check.
"Getting another crack at Kilmacud 12 months later was obviously going to be a driving motivation for us and we felt like we had a fantastic first half but the players that Kilmacud have in terms of [Paul] Mannion and [Shane] Walsh to be able to flip a game on its head.
"I wouldn't say it was a monkey off our back but there was a bit of fulfillment to be able to rectify the defeat.
"But it was a semi-final at the end of the day. Yes, we got one over on Crokes after last year. But we haven't won anything.
"It was a matter of getting off the field and not celebrating too much. That was Malachy [O'Rourke] driving that.
"After we won our first Derry championship, we played St Eunan's, Letterkenny two weeks later and we had a terrible performance and just about scraped past that game.
"We know that if you dwell too much on your last performance and overhype, it's only going to negatively impact your next performance.
"Brigid's are the most in-form team in the country and we have a hell of a challenge to get over them this weekend."
While Glen are the favourites and have been rapping harder at the door in the 2020s, the Roscommon champions boast the more illustrious history, the Frankie Dolan point to win the 2013 All-Ireland final against Ballymun Kickhams etched in competition folklore.
"If you look back at their last three or four games, they dismantled Corofin in the first 10 minutes of the first half and that's a team that was pipped to win the All-Ireland this year.
"Castlehaven was no easy challenge so they're a serious talent. They're more successful than we are; they won the All-Ireland 10 years ago so they've been there and done that.
"That's invaluable to that club. The tag as favourites is good to have but it doesn't effect our preparation and the way we go about it."
Brigid's also availed of the opportunity to train at GAA HQ immediately after the junior and intermediate finals last Sunday. Glass confirms that Glen were also offered the option of training in Croker but logistics wouldn't allow it, and anyway, they have ample experience of the venue from last winter.
The former All-Star midfielder has barely stopped since returning from his AFL stint with Hawthorn in 2020.
He even trooped out in Derry's opening League game last year - a facile win over Limerick - while confusion still reigned over whether the All-Ireland club final was going to be replayed.
Unusually, Glass combines it all with being a small business owner, running a cafe in Maghera.
"It's a getaway from football, although customers who come in just want to chat about football! So it's a bit of both.
"I love the business side of it. It's a passion of mine and thankfully, I have a fantastic partner and girlfriend in Niamh. She's able to run the cafe when I'm playing matches or training at the weekend.
"A cafe is the heartbeat of the community and it'll be bouncing this week with people wanting to come in and chat about football. Thankfully, I'm able to provide that service to the community."
