Cork Triathlon 70.3

The Cork Triathlon 70.3 is what happens when a city with rebel county racing with Irish craic hosts the world's most raced long-distance triathlon. Race morning in Cork starts early. The 1.9km swim sends you into frigid river at 12°C — cold enough to steal your breath on entry. 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 centrepiece: rolling with some honest climbs terrain with 578m of climbing that never lets you settle. At 70.3 distance, the bike is where races are won and lost — 90km of rolling road demands constant effort management. The 21.1km run rolls through Cork, adding 86m of climbing to legs already tested by the bike. The undulations are psychological as much as physical — each rise feels larger than it is when you've been racing for four hours. A 70.3 that rewards the athletes who trained specifically for this distance, not just those who scaled down from Ironman.
