How to choose a marathon training plan
The right plan fits your current running, the days you can train, and the time you need to recover. It should feel repeatable for the full build, not impressive for one week.
Choose the plan length
- If you are new, returning, or still building consistency: consider 20–24 weeks with fewer hard sessions.
- If you already train consistently and recover well: 16–20 weeks may be enough.
- If your schedule changes often: choose fewer running days and protect the long run rather than forcing every optional session.
Check your starting point
- You can complete the plan's early easy runs without straining.
- Your recent weekly training is reasonably close to the opening weeks.
- You have enough time for sleep, meals, and recovery around the longest sessions.
- You are willing to keep easy runs conversational.
Mistakes to avoid
- Turning easy runs into medium-hard runs.
- Adding intensity to compensate for a missed session.
- Treating long runs as races.
- Choosing more training days than your normal week can support.
A simple weekly pattern
- One controlled quality workout.
- One long-run focus.
- Easy running between harder sessions.
- Short strength work placed where it does not compromise key runs.
