IRONMAN Belgium Knokke-Heist 2027
A full-distance race at Knokke-Heist: a swim in the Damsche Vaart, a bike route still to be published and a two-loop run along the beach and the Zeedijk.
48 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 bike route was not yet published when this page was written, so build general endurance and revisit once the organiser releases it. The run is two loops along the beach and the Zeedijk.”

Not yet confirmed for this edition: bike elevation gain, cut-off times, aid station spacing, water temperature history, course maps (not checked against official GPX), bike route. We publish these only once they are on the official course page, so check there before you pace off anything here.
