A 16-week progressive build to a full marathon, structured around a weekly long run, easier supporting mileage, and a taper. It assumes you can already run comfortably for around 30 minutes. If you're starting from less than that, spend a couple of months building a base first — 16 weeks from zero is how people arrive at the start line injured.
The single most common mistake in marathon preparation is running the easy days too hard, which leaves you too tired to run the hard days hard enough. If you can't hold a conversation on an easy run, you're going too fast. This feels wrong for weeks and then stops feeling wrong.
Everything else supports it. Build it gradually — a rough ceiling of about 10% growth per week, with a step-back week every third or fourth — and practise on it: the shoes, the socks, the fuel, the early alarm. Nothing on race day should be new.
Most people can't absorb enough during a marathon without training the gut to tolerate it. Take your planned race fuelling on the long runs, at the intervals you'll use, and find out early which products disagree with you.
The final weeks reduce volume sharply and it will feel like losing fitness. It isn't; it's letting accumulated fatigue clear so the work shows up on the day. Nothing you do in the last fortnight makes you fitter, and plenty of it can make you slower.
Turn on due dates and set the start date exactly 16 weeks before race day.
