IRONMAN 70.3 Mallorca 2027
The largest 70.3 in the world. A sheltered Alcudia Bay swim, a bike into the Serra de Tramuntana, and a flat coastal run, with 3,700 athletes from 100 countries.
38 weeks to race day: base season
Plenty of runway. This far out, the win is a boring, consistent base rhythm: aerobic volume, strength, technique. The structured block starts closer in; what you do now decides how high it can climb.
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.
Build my complete road.
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 biggest 70.3 on earth and a genuine cyclist's course. If you have ever done a Mallorca training camp you already know whether you will love this bike leg.”
The race
The course
Inside the Bay of Alcúdia, well protected from open sea, starting and finishing at Playa d'Alcúdia. White sand and turquoise water, and genuinely sheltered, so conditions are rarely the problem here.
One lap from the bay into the Serra de Tramuntana, over the Coll de Femenia. 800m of climbing on a half distance is a lot, and it is concentrated rather than spread, so this is a course you pace by the climb, not by the average.
IRONMAN publishes no route file for this leg, so there is no course map to draw from.
Three flat laps around Alcúdia, over bridges and canals with the bay in view, finishing on the beach about 50m from where you started swimming. A neat circle to close the day on.
Not yet confirmed for this edition: swim lap count, cut-off times, aid station spacing, water temperature. We publish these only once they are on the official course page, so check there before you pace off anything here.
