40 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.
“This is a climbing race with a swim attached. Ride the first bike loop slower than feels right, because the run is hilly too and it will take back anything you spend early.”

The course
No course maps for this race. IRONMAN publishes no downloadable route for any leg of this race, so there is nothing to draw a course map from. Everything below comes from the official course page, checked on the date at the foot of this section.
Two loops of Mirror Lake. Use the organiser's current course information as the authority for the final buoy layout and race-week instructions.
Two loops through the Adirondacks, with sustained climbing and descending. The Keene descent makes controlled pacing and bike handling part of the preparation.
Two hilly loops through Lake Placid, finishing on the Olympic speed skating oval. Check the current athlete guide for the final route and access details.
