Massive shout-out to David Cahill, who took on the National Aquathlon Championships and came away as 🥇 Age Group Champion! Swim? Smashed. Run? Smashed. Age Group? Claimed. 😎 An absolutely brilliant performance and a very well-earned national title. 🏊‍♂️🏃🧡🇮🇪

Massive congratulations to our 3D crew at the Tour de Kilkenny! 🧡 One rider conquered the 110km route, while three took on the full 160km challenge, tackling over 2,000m of climbing. An incredible day’s cycling, supporting a fantastic charity event and making memories together. Chapeau, everyone! 🚴💪 🧡 Gardaí reported plenty of speeding across Kilkenny this Bank Holiday weekend… 👀 We can neither confirm nor deny that four orange jerseys were responsible for some suspiciously quick Strava uploads… 😅 No cyclists were fined during the making of this reel… as far as we know. 😂🚴🧡
