There is a new fashion in Irish athletics, and a new star to go with it.
It's about 20km race walking, and by winning the silver medal at the World Championships in Paris yesterday Gillian O'Sullivan has in one great effort taken the event into a different era.
Certainly before this achievement the event in Ireland was enjoyed only by a handful of competitors, and followed by only the desperately curious.
There may not be kids rushing out to imitate the almost impossible techniques, but O'Sullivan has now earned the respect of the best in the world and will come away from Paris $60,000 richer. This medal, too, should be just a stop-off in her journey to the very top of the world. She surrendered the gold medal yesterday to Yelena Nikolayeva, who at age 37 is 10 years O'Sullivan's senior.
And the Russian has long been known as the most successful woman walker in history, with several Olympic and World medals already in her possession.
For O'Sullivan, it was the breakthrough she has been so diligently pursuing - a coming-of-age performance after years of steady progression. She arrived into the Stade de France after the 20km circuit on the Paris streets with the face of a champion, all smiles and punching the air.
"I kind of felt it was going to be good today," she said afterwards. "I woke up feeling good. And I was ready for this. I'd prepared so well all year, and trained so hard. And had some really good races before coming here."
In fact the Kerry athlete, born and raised in Killarney, had the silver medal firmly around her neck well before the halfway mark. Nikolayeva had broken clear, but the gap back to third was even greater. O'Sullivan merely had to contain her seemingly effortless technique.
"Well, of course, these races are never easy. In a way I had expected to win this medal, but you have to hold yourself together because it can all go out the window in a second. When we did break away so early I knew others might still come through, because I'd done that before myself."
But she had nothing to fear.
