🏊 SWIM. 🚴 BIKE. 🏃 RUN.
This is the game I have wanted to exist for years. Nobody made it. So I built it.
IRON CIRCUIT is a rhythm-based triathlon game with real distances from four of the most iconic courses on the planet — Sydney, Tokyo, Nice, and Kona. You tap in rhythm to swim, pedal, and stride. You manage your energy across three disciplines. You race against 7 AI opponents who each have their own strategy.
The part that gets me every time is The Wall. You are at 70% of the run. The screen darkens. Your speed drops. Your energy drains. You have to decide — do I push through or do I conserve and hope the AI fades too? That decision changes every race.
My first completion of the Kona Iron distance took me by surprise. 3.8km swim, 180km bike, 42.2km marathon. When the finish line appeared and the crowd kicked in, I genuinely felt something. That is what triathlon does to you.
Tips for new racers: save your sprint for the final 5% of the run. Hit the aid stations with E. Draft behind AI opponents to save energy. And learn the rhythm — PERFECT hits cost almost nothing and give maximum speed.

Race hard. 🥇
