45 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.
“Regularly voted one of the most beautiful 70.3s in the world, and it earns the climbing. Get comfortable riding at 1,200m before you go.”
The race
The course
Interactive swim route in the Course Lab above ↑ Drawn from the official GPX file, checked against this leg's distance.
Lake Zell, ringed by Alpine peaks. Alpine lake water is cold whatever the air temperature is doing, and that is the single thing to prepare for here.
Interactive bike route in the Course Lab above ↑ Drawn from the official GPX file, checked against this leg's distance.
A demanding course through rugged mountain terrain with real climbs and fast descents. This is the hardest half distance bike in the region and the descents are as much of the challenge as the climbs.

Along the shore of Lake Zell, flat and fast, which after that bike is either a relief or a reckoning depending on how you rode.
Not yet confirmed for this edition: lap counts on all three legs, bike elevation gain, cut-off times, aid station spacing. We publish these only once they are on the official course page, so check there before you pace off anything here.
