IRONMAN 70.3 Cartagena 2026
A 70.3 at Cartagena on Colombia's Caribbean coast: a swim in the Bahía de las Ánimas, a 90 km bike and a two-loop run through the Old City.
8 weeks to race day: a full block fits
This is the sweet spot. A complete 12-week recovery-led build fits inside the runway with room for a base phase in front. Anchor the block to race day and every week between now and then has a reason.
Building for this one? 70.3 training plan covers the sessions, the weekly shape and how the block is paced. The R.A.C.E. Framework explains why it is built that way.
Adapt my training to this course.
Commit to the date and the work gets a shape: your countdown starts, the emails arrive in step with your build, and the app anchors a recovery-led block so the final week lands exactly on race day.
One confirmation email, then the road begins. Registering for the race itself stays with the organiser.
“The run is two loops through Cartagena's Old City, so plan for heat and humidity and practise running in them. The organiser publishes no bike route detail on the pages read.”
