How this Marathon running plan works
This Marathon running plan uses a 16-week build to prepare you for 42 km with weekly mileage that generally lands in the 55-85 km range. Long runs build toward 24-34 km, so the training load stays aligned with the demands of the distance.
Prioritize aerobic durability, fueling practice, and disciplined pacing so the long run supports the full race instead of just the first half. Expect steadier weekly volume, longer long runs, and more discipline around pacing and recovery as the race gets longer.
