Your day in Coeur d'Alene
What could you race?
I’m Tom, the coach behind Sense Endurance Coaching. Tell me where you are now and I’ll show you what a strong day in Coeur d'Alene could look like.
The course behind your race
The bike should still feel unfinished when you return to City Park.
Coeur d'Alene is not a course to prove fitness on every harder section. Keep the ride as one continuous effort so the two lakeside run loops begin with choices still available.
North and west sides of the lake · first half
Let the harder terrain come to you.
The challenging bike rewards a steady ceiling. Let speed fall when the road asks for more rather than defending a target pace.
Cap opening effort. Fuel early.
Return towards Coeur d'Alene City Park
Keep the final bike kilometres inside the same effort.
Keep the second half inside the same effort and finish planned nutrition before the two-loop lakeside run.
Stay patient. Finish planned nutrition.
Historic neighbourhoods and lakeside · first loop
Run the first loop as a check, not a verdict.
Let the historic-neighbourhood opening feel easy, not fast.
Easy first aid station. Check posture.
Lakeside return · second loop
Build only when your stride still has shape.
Only progress once the first loop has held together.
Stay tall. Choose the last move late.
What to check in race week
Check the lake-swim direction, bike and run turns and City Park access when the final race-week details arrive. Let the forecast and the conditions you meet guide clothing, hydration and tyre pressure, rather than assuming the lake or roads will behave like last year.

Your plan, in race week
Prepare for Coeur d'Alene
Build the legs.
Practise the decisions.
A finish range gives you something to work towards. The preparation is specific to this race: Prepare to hold a ceiling on harder bike terrain, fuel while the effort is controlled and begin the run without immediately matching the pace around you. The skill Coeur d'Alene asks for is keeping a scenic course from turning into a sequence of small races.
I’m Tom. With Sense Endurance Coaching, I’ll build that preparation around your life, follow how you respond and adjust the work as you get closer to Coeur d'Alene.
