A marathon is 42.195 km (26.2 miles), and preparation is about consistent training, resilience and execution as much as speed. Choose a plan based on your recent mileage, longest comfortable run, available time and experience—not just the number of weeks until race day.
Build a durable base
Before a dedicated marathon block, establish a regular routine that you can recover from. Most running should be easy. Long runs build time-on-feet, while recovery days allow adaptation. Avoid making large jumps in distance, intensity and frequency simultaneously.
Use quality sessions carefully
Some experienced runners include marathon-pace segments or threshold work. These should complement—not replace—easy running. Beginners can prepare successfully with mostly easy running and a conservative run/walk approach.
Long runs and fuelling practice
Gradually extend long runs according to your plan and recovery. You may not need to cover the full marathon distance in training. Practise your race breakfast, fluids and carbohydrate products on long sessions. The fuelling planner estimates totals from a chosen hourly target, but individual tolerance varies.
Choose a realistic pace
Use recent race performances and training evidence. Predictions are only estimates, and marathon outcomes are sensitive to endurance, heat, wind, elevation and fuelling. Start conservatively and reassess after halfway rather than trying to bank time early.
Taper and logistics
Reduce volume in the final weeks while keeping runs familiar and manageable. Check transport, start pens, cut-off rules, bag drop, toilets and course aid stations. Lay out tested kit and avoid new shoes or foods.
When the race gets difficult
Break the course into manageable sections, take aid stations calmly and keep effort steady. If you feel unwell, dizzy or experience concerning symptoms, stop and seek event medical support. Finishing safely is more important than protecting a target time.
Recovery
Plan several easy days and return gradually. Sleep, regular meals and gentle movement support recovery. Do not rush into another demanding block while fatigue or pain persists.
Build the base before the big miles
Marathon training is easier to absorb when you already run consistently. Increase weekly load gradually, schedule recovery weeks and avoid adding extra mileage to compensate for a missed session. A plan should match your running history and available time.
Long runs, goal pace and recovery
Long runs develop time-on-feet and fuelling habits; selected goal-pace blocks can teach control. Not every long run needs to be fast. Keep recovery runs easy, sleep well and adapt the plan when fatigue accumulates.
The taper
In the final weeks, reduce overall volume while keeping some familiar, light intensity if appropriate. Do not try to gain last-minute fitness with a huge session. Practise breakfast, kit, pacing and fuelling before race day.
Marathon-day pacing
The first few miles should feel restrained. Be prepared to adjust your target to weather, terrain and how you feel. A steady effort often serves runners better than aggressive early pace followed by a large slowdown.
