About the 13-Week Full marathon (Intermediate)
A 13-week plan to run a strong marathon, written for the Intermediate level. It starts where you are, adds load gradually and mixes easy running with targeted sessions so you peak on race day.
Pick this quest if you run regularly, have finished this distance or close to it, and want a stronger, faster race. If that sounds too easy or too hard, choose a different level of the same goal below.
How the plan is structured
| Phase | When | Focus |
|---|---|---|
| Base | Weeks 1–4 | Easy aerobic running and strength work. Most runs at a conversational pace. |
| Build | Weeks 5–9 | Longer long runs plus one quality session a week: tempo, intervals or race-pace segments. |
| Peak | Weeks 10–11 | The longest long runs and the most race-specific sessions of the plan. |
| Taper | Weeks 12–13 | Volume drops, a little intensity stays, so you start fresh and sharp. |
What a typical week looks like
