🥇 Medal Monday… brought to you by what can only be described as Costa del Ireland 😎 What a weekend for our 3D athletes, who were out racing, swimming, cycling, smiling, and collecting medals all across the country — all while somehow enjoying unreal sunshine from Galway to Kerry to Kildare ☀️ At the Lough Cutra Castle in Galway, our athletes took on the Olympic distance with brilliant performances, strong racing, and even a podium appearance 👏🏆 Meanwhile down in Kerry, riders tackled the mighty Ring of Beara Cycle — 140km & 110km of stunning roads, climbing, questionable life choices, and somehow still enough energy left for smiles (and medals!) at the finish 🚴‍♀️😅 And over in Kildare, athletes took to the water for SwimAthy, proving once again that voluntarily swimming outdoors in Ireland is apparently considered a hobby 🏊‍♀️😂 In fairness, what weekend for outdoor swimming! Huge congratulations to every single athlete who represented the club this weekend. Different events, different challenges, but the same brilliant club spirit all around 🧡 Safe to say we had: ☀️ Costa del Galway ☀️ Costa del Kerry ☀️ Costa del Kildare …all we were missing was the sangria 🍹😜

Still on time for a #tbt: A huge well done to all of our athletes who took part in the Irish Runner 5k on last Saturday, 16th May, as part of the Athletics Ireland Race Series 2026. The club delivered seriously strong performances all round, with plenty of PBs flying in left, right, and centre 🔥 Safe to say the training is working… although some people may now become absolutely unbearable on Strava for the next few weeks 😅 The event was brilliantly organised, the atmosphere was fantastic, and the Irish weather was perfect for a morning race. And fair play to the organisers — the medal was actually class too 🏅 Well done everyone — great racing, great club spirit, and another brilliant morning for the club 👏🧡

⏰🏃‍♀️ Slightly late post… but in our defence, everyone has been too busy training, racing, recovering, foam rolling, checking Strava, and pretending to stretch 😅 Back on the 3rd of May, a fantastic group of our 3D athletes took on the Dublin Half Marathon, with some brilliant performances across the board — including a few shiny new PBs! 💪🔥 Massive congratulations to every single athlete who lined up, pushed through the kilometres, and represented the club so well. Whether it was chasing a time goal, enjoying the atmosphere, or simply surviving the final kilometres, every result deserves celebrating 🧡 And on the same day, while we’re catching up… huge congratulations as well to one of our athletes for taking 3rd place at the Hills Cameron 10k! 🥉 Although judging by the photo, we’re still not entirely sure if the podium or medal was the actual prize… or if the baby was included in the winnings 👶😂 Well done everyone — serious performances, great club spirit, and plenty more to come! 🚴‍♀️🏊‍♂️🏃
