Challenge Almere-Amsterdam 2027
A long and middle-distance triathlon at Almere: a counterclockwise swim in the Weerwater, a flat polder bike and an urban and lakeside run.
49 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? Ironman 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 organiser describes a flat polder bike on open roads, so wind and even pacing are the main challenges. The run is made of 10.1 km laps.”
