He finished the 2014/2015 National Hunt campaign with a perfect record by taking the Punchestown Champion Hurdle and was marked by the Anglo-Irish and Timeform handicappers as the highest rated hurdler in training.

[8] He ran his first race in a point-to-point circuit in the colours of Thomas Hassett, who named him after a church near the Bohernamuck crossroads in County Waterford called Faugheen Chapel.

Ridden by his trainer's son Patrick Mullins, he started 11/8 favourite and accelerated clear of his opponents in the last quarter mile to win by twenty-two lengths from Josses Hill.

Ruby Walsh beforehand said that Faugheen "absolutely bolted up at Punchestown on his first run of this season and the third, Oscar Chimes, won since in Thurles, so the form doesn’t look too bad" and reported that he had "worked really well during the week and is, without doubt, the reason I’m staying at home.

[17] On 28 December Faugheen was moved up in class for the Dorans Pride Novice Hurdle graded event over three miles on heavy ground at Limerick Racecourse.

By this time, the previously beaten horses started to frank the form, leading with the bumper 22 lengths runner-up Josses Hill who was purchased for £100,000 and subsequently won his next 2 races,[18] therefore the raise in class proved of little concern and Faugheen "maintained his unbeaten record in effortless fashion when taking the Novice Hurdle at Limerick".

"[2] Ruby Walsh tracked the front-runner Cole Harden before taking the lead at the third last at which he blundered but managed to stay upfront putting in another awkward jump at the second last hurdle while horses from off the pace were starting to make their presence felt in behind.

At the turn Walsh asked his mount for the final effort and Faugheen responded by steering away from his rivals and finishing four and a half lengths at the line ahead of Ballyalton and Rathvinden who were both kept off the pace throughout the race.

After this race the already popular nickname "Faugheen The Machine" started to officially get used in news articles [2][22][23][24] and in live commentaries e.g. Channel 4 commentator on Boxing Day.

[25] Faugheen's final appearance of the season was on 29 April and started the 1/2 favourite when dropped down in distance for the Grade 1 Herald Champion Novice Hurdle over two miles at the Punchestown Festival.

"[43] Coming into the home straight Faugheen found the extra gear and pulled clear of his rivals[44] never looking in danger with his stablemate third-string Arctic Fire the closest finisher and flattered by the margin at the line after being kept off the pace throughout the race: "He was a length and a half behind, but Walsh felt his mount was idling having been in front for so long".

The former Champion Hudlers Hurricane Fly and Jezki were routed to the staying division after failing to make an impression against Faugheen last time out at Cheltenham, while the runner-up that day Arctic Fire was the only credible danger in this race.

[29] After winning the 2015 Champion Hurdle, Willie Mullins said: "There's no reason to go novice chasing when you have a hurdler as good as this"[50] and later confirmed that Faugheen "won’t jump a fence for a long time, perhaps ever".

[51] In mid-October 2015 in an exclusive interview on At the Races owner Rich Ricci revealed that "Faugheen looks like a chaser, we all know that, but he has a sensitive back and was hard to keep fit as a younger horse, hurdling probably is the right way for him".

[52] Faugheen made his return on 15 November 2015 in the Morgiana Hurdle [53] and while the general racing public expected a clean sweep by the champion hurdler who was sent off as the 1/6 favourite, instead a "shock defeat"[54] left even his trainer Willie Mullins surprised when Faugheen's stablemate Nichols Canyon, a two-times Listed flat winner in 2013 and four-time Grade 1 winner in his 2014/2015 novice season, took the lead and remained in the first spot for the rest of the contest.

During the race, the tactical slow gallop set by jockey David Mullins did not help Faugheen's jumping as he awkwardly skipped over the third obstacle and a significant error at the second last hurdle put another two lengths between himself and his stablemate.

"Faugheen's 11-race unbeaten run ended" [55] Sprinting for home the three Mullins-trained horses were all in contention, including Wicklow Brave who on his previous three starts finished third in the G1 Irish St. Leger and G2 British Champions Long Distance Cup, placed second in the Ebor, Europe's most valuable flat handicap and was an eight lengths winner at the Cheltenham Festival in the 2015 County Hurdle.

[56] Furthermore, while Ruby Walsh's prediction a month earlier: "Faugheen's unbeaten over timber but somewhere along the way that may go"[58] came true on his reappearance, the jockey found the actual defeat discouraging: "It's disappointing, he didn’t pick up like he can, but that's horse racing isn’t it?

After two more furlongs Nichols Canyon showed the first signs of getting tired following Faugheen's strong gallop and jumped the second last hurdle markedly to his right with jockey Paul Townend pushing along whilst Arctic Fire passed him.

[68] With his forced retreat for the campaign, Mullins was still left with the front three challengers in the Champion Hurdle market but his retained jockey Ruby Walsh explained: "It's like someone whipping the ace out of the pack and handing you the rest of the cards".

[69] The injury followed the roller coaster events of Faugheen's season that started with the surprise defeat on reappearance and succeeded with the latest performance for which he was rated the best two-mile hurdler of the century by the official handicappers, as well as the private organizations Timeform[70] and Racing Post.

Faugheen's usual rider Ruby Walsh was injured the previous day and was replaced with former Irish champion jockey Paul Townend who had never ridden him in public.

He set off a good gallop on Faugheen from the start and showed his ability was intact by winning hard held 16 lengths back to Jezki who was also well clear of the rest.

In the next couple of weeks he was examined and passed a number of tests but no issues were discovered which left his trainer Willie Mullins perplexed as to the cause for the substandard outing, thus aiming him at the Dublin Racing Festival to regain the Irish Champion Hurdle declaring "I'm hoping that if he works well at home and if nothing else comes up, I won't have any worries".

"[76] In March 2018 Faugheen returned to Cheltenham and resumed his partnership with Ruby Walsh in an attempt to regain the Champion Hurdle title three years after their victory in 2015, having missed the race in 2016 and 2017 due to injury.

"[78] As in previous seasons, Faugheen made his reappearance in the Morgiana Hurdle on 18 November 2018 at Punchestown, ridden by Ruby Walsh and sent off as odds-on favourite with only three rivals.

Amidst injury concerns, his form started to drift but Ruby's bond with the horse was clear – amicably pulling him up and dismounting at the slightest sign of Faugheen not seeming himself at Aintree this year.

But his connections had other plans, and in October 2019 trainer Willie Mullins announced that Faugheen would be joining the ranks of novice chasers for the 2019/2020 National Hunt season.

[85] His next outing was the Grade 1 Greenmount Park Novice Chase at Limerick, where he was ridden by his trainer's son Patrick Mullins and started second favourite to Samcro.

[90] 1 Dorans Pride Novice Hurdle was upgraded to Grade 2 in 2015 after Faugheen and Martello Tower subsequently won at the Cheltenham Festival in the same season.
