IRONMAN Cartagena
IRONMAN 70.3 Cartagena is on 29 November 2026. The 1.9 km swim is in the bay, the 90 km bike is flat, and the 21.1 km run goes through the walled colonial city on Colombia's Caribbean coast.
Late November here is hot and humid, and the old town has stone underfoot with buildings that hold the heat well into the day. The run decides your race, not the bike.
Set against that, it is one of the easier long-haul races to justify to whoever is travelling with you. The walled city is compact and walkable, the airport is minutes from the centre, and there are direct flights from several US cities.
Stay inside or just outside the walls if you would rather not organise a taxi for four in the morning on race day.
