Naples Triathlon 70.3

The half-iron distance asks a particular question: can you hold race pace for five-plus hours across three disciplines? In Naples, the course adds its own follow-up questions. The 1.9km swim sends you into cold ocean at 13°C — bracing — the kind of cold that sharpens focus. It's long enough that a poor start costs real time, short enough that strong swimmers can build a genuine lead. The 90km bike is the defining leg: 993m of elevation gain across a mountainous course that separates those who trained for this specific distance from those who just showed up fit. Ninety kilometres of climbing changes the race equation entirely. A rolling half-marathon through Naples with 148m of gain. After 90km on the bike, even gentle rises feel significant. Quick cadence on the ups, controlled effort on the downs, and trust the training through the middle kilometres. Half-iron done right: long enough to demand respect, short enough to race hard from start to finish.
