Readiness
Start with the runner you are today.
A 14-18 week block can work well if summer base is already present.

Use the CIM build to turn fall fitness into a controlled marathon block.
CIM can be quick, but a net-downhill profile still asks for resilient legs, consistent mileage, and a plan that adapts when recovery dips.
Pacing
Weather changes the training target.
Fall training may start warm and end cool. Use the same effort logic across changing weather.
Adjust paceCourse
Train the demands, not just the distance.
Rolling early miles and late fatigue make pacing discipline more useful than chasing every downhill split.
Check load01
Confirm the base
Use weekly mileage, long-run comfort, consistency, and current pain signals before choosing a marathon plan.
02
Protect the hard days
If heat, poor sleep, HRV, or load spikes stack up, adjust intensity first instead of forcing the planned split.
03
Keep gear boring
Estimate shoe replacement before peak mileage so race shoes and daily trainers are not surprise decisions.
04
Close the loop
Send workouts to Apple Watch, bring completed runs back, and let the next week respond to what actually happened.
A race plan should adapt before race day.
