As with any seminal moment in Irish sport there is always the danger that some of the power and the beauty has been exaggerated over time. That’s not necessarily so in the years since Phil Healy helped blaze the relay trail with such unforgettable levels of excitement, the likes of which we may never see again.If anything, Healy’s were the sort of moments that will only get better with age – starting with the one where Healy came from “the depths of hell” in an otherwise inconspicuous climax to the 2016 Irish Universities track and field championships in Santry. The perfect sporting blend of raw excitement and blissful innocence, Healy’s anchor leg for UCC in the women’s 4x400m relay that day still creates proper chills of excitement. Especially in this heatwave.Which might also explain why the original clip on YouTube has more than 3.5 million views ... and counting.Healy wasn’t within sight of the lead runners chasing down the backstretch and was still only fifth coming into the homestretch, before hauling herself over the line in first, delighting her UCC team-mates. In fairness, the hysterical race commentary by Cathal Dennehy, assisted by Ronan Duggan, elevated the madness, Dennehy describing Healy’s late surge as coming from “the depths of hell” – a poetic reference Dante himself would have been proud of.It was the giddy reminder among the many tributes to Healy after she announced her retirement from international athletics on Tuesday. A two-time Olympian, European relay bronze medallist, and once undisputed as Ireland’s fastest woman over 100m and 200m, her commitment and dedication to the relay also helped set her apart. Especially when Irish relays were somewhat less fashionable.Healy was 21 at the time of the UCC relay leg, moving up to the 400m for the first time too. It certainly helped raise her profile – the clip ended up on Good Morning America and ESPN – but also it marked a significant turning point in Irish athletics history. With an athlete like Healy in a relay team, suddenly anything seemed possible.Phil Healy passes the baton to Ireland team-mate Sophie Becker during the final of the mixed 4x400m relay at the Tokyo Olympics. Photograph: Morgan Treacy/Inpho Fast-forward five years, and Healy was part of the Irish mixed 4x400m relay team that made the final at the delayed Tokyo 2020 Olympics – a first for any Irish relay team. She also competed in two individual events in Tokyo, the 200m/400m. But if the fresh possibilities of Irish relay running were beginning to shine, athletes still needed to buy into them.There were two further marks of relay progress. The women’s 4x400m finished sixth at the 2022 European Championships in Munich, and the women’s quartet then made the 4x400m final at the 2023 World Championships in Budapest. Healy, however, withdrew from Budapest, having originally been selected, realising herself that between illness and injury she was simply off her best.If a big part of relay running is being able to step up, it’s also important to know when to step away. Healy understood that too. In the selfishly driven world of athletics, she was the consummate team player. She was respectful, too, in the way she’d always show up at the National Championships, winning 17 senior titles in all.Growing up in the village of Ballineen, outside Bandon in Cork, there were several other standout components of her career that came to light this week. Proof and a reminder of what is possible for an entirely home-produced athlete, with an essentially voluntary coaching set-up led by Shane McCormack, once the attitude and application is right.[ Phil Healy: ‘I didn’t know if I would ever get back to where I was’Opens in new window ]In an interview with this newspaper in February 2024, Healy admitted she’d contemplated retirement “many times” in the previous 18 months. Basic sprint sessions had become such a slog, her racing form so brutally inconsistent, it didn’t seem like there was any easy way back, having also been diagnosed with the autoimmune disorder Hashimoto’s disease.Fast-forward another four months, and Healy was part of the Irish women’s 4x400m that won silver at the European Championships in Rome. Truth is, they needed Healy back to her best. Then two months later, the same quartet finished just .18 of a second off Olympic bronze in Paris 2024.Of all the fourth-place finishes in Irish Olympic history – and remember there have been many – this was unquestionably among the least expected, the quartet of Sophie Becker, Rhasidat Adeleke, Healy and Sharlene Mawdsley also taking three seconds off the Irish record. Part of the surprise was that they qualified for the final in the first place – without Adeleke remember – who had also finished a close fourth in the 400m final the night before.It could be a long time before another Irish relay team comes that close to winning an Olympic medal. That’s not being deliberately pessimistic, but something about the way that quartet came together that night in Paris was unique – and certainly can’t be easily planned for again.Because while Healy steps away, Mawdsley continues to step up in her individual aspirations. Last Sunday Mawdsley came within a few strides of winning the biggest 400m of her career when finishing second at the FBK Games. For the third time this season she also improved her 400m best, running 50.14 seconds, within clear reach now of the 50-second barrier.Rhasidat Adeleke and Phil Healy at the Paris Olympic Games 2024.

If she makes the 400m final, and she is eminently capable, it’s unlikely she’ll race the heats of the 4x400m relay, which take place the day before.Adeleke’s form remains unknown, although she is scheduled to have her first 400m race in over a year in Eugene next Saturday. If that goes well, she will also run the 400m at the Monaco Diamond League on July 10th.Healy, meanwhile, owes Irish relay running absolutely nothing, and although the future looks a little more uncertain without her, she’s always been exemplary in showing the way. The baton is passed.
