A winter-to-spring block usually needs 14-18 focused weeks after a stable base phase.
Check readinessBoston is not just a fitness test. It asks for eccentric strength, pacing discipline, and a plan that does not turn every workout into proof.

Check readinessSpring race weather can swing. Train the plan, then use effort and conditions to make the final pacing call.
Adjust paceEarly downhill miles can cost more than they feel. A useful Boston plan prepares the legs for downhill load before the late hills arrive.
Check loadUse weekly mileage, long-run comfort, consistency, and current pain signals before choosing a marathon plan.
If heat, poor sleep, HRV, or load spikes stack up, adjust intensity first instead of forcing the planned split.
Estimate shoe replacement before peak mileage so race shoes and daily trainers are not surprise decisions.
Send workouts to Apple Watch, bring completed runs back, and let the next week respond to what actually happened.
