Your goal
Same starting point for each; change it under “Adjust this plan”.Your 16-week finish well plan
The plan starts Monday 9 November 2026, 5 weeks from now. Until then: base weeks from this week or a half marathon on the way.
Which one?
Base weeks: mostly easy running at the volume you run now, then this plan, in one calendar with a "what do I do today". Same runner, same plan. If you follow the Evergreen plan, these base weeks are that plan.
A half marathon four to six weeks before the marathon is the classic build-up: a fitness check and race practice that sets your marathon pace. The list shows halves three to eight weeks out; pick one and the season planner fits it into this build.
Or keep this page: it shows the same plan until Monday 9 November 2026.

Plan assumptions and limits
- Road race: the plan is distance-driven and no vertical target is prescribed.
- Generic planning guidance from race facts and stated training — not medical care or individual coaching.
- Training distances and durations are approximate alternatives, not pace targets. Use current effort, not a hoped-for finish time. Repeat or shorten a week if recovery is poor; do not make up missed sessions.
