Intermediate Marathon Training Plan
Written by Andrew Taylor. USATF Level 1 Coach. Coaching runners since 2010.
Build the strength to manage the whole marathon.
Your running is consistent and structured. This 20 week plan is designed to build the durability you need when the closing miles test you and the pace stops feeling automatic.
By scaling from 18 to 52 miles across 6 runs a week, you will develop the deep structural strength required to maintain your goal effort even when your legs are no longer fresh.
The training is intentionally build around two long run efforts to sharpen your race day pace, ensuring every demanding effort has a clear, performance-driven purpose.
Because most of your running stays strictly controlled, the plan protects your recovery, allowing you to absorb the heavy workload and finish the marathon reflecting the true depth of your training.
- 20 week plan
- 6 runs per week
- 30 to 52 miles a week
- Longest run 20 miles
- 120 coached runs

Is This You?
If you run 4 days with a long run around 6 miles and no weekly workout, choose the Beginner Marathon. If you want more volume and a second workout every week, choose the Advanced Marathon.

Two Long Runs Build Durability
At mile 20, you are not out of breath. Your legs just stop producing what they gave you an hour earlier. The effort feels familiar, but the stride behind it is disappearing. That is what the last hour takes away.
The obvious response is to make the long run bigger. If 20 miles emptied you out, run 22. But a single run large enough to build what is missing costs days of recovery, and those days come out of the rest of the week. You get one heroic run surrounded by less training.
Thursday adds real time on your feet without the same recovery cost because it stays easy and never carries an effort finish. Saturday then begins on legs that have already gone long that week. That is the condition the closing miles of a marathon put you in.
Or have the plan written as you go
This plan is fixed the day you buy it. A marathon build is not, and neither is the life you are fitting it around. With coaching, Andrew reads what you ran, what hurt and what got in the way, then writes the next 4 weeks against it rather than against a template.

What Makes A Sunrise Running Plan Different
Most plans tell you how far to run. This one tells you how it should feel, and what to do when it doesn’t.
More on why this Sunrise Running plan runs on effort instead of pace.
A Real Week From The Plan
Week 17 brings both long runs to their peak and makes Saturday a complete race rehearsal.
| Day | Session | Time | What It Asks For |
|---|---|---|---|
| Monday | Easy Run Plus Strides | 55 minutes | Run easy, adding 4 to 5 relaxed strides in the second half. |
| Tuesday | Marathon Effort Workout, Strength and Mobility for Runners | 60 minutes + 20 minutes | Run 20 minutes easy, 18 minutes at marathon effort and 22 minutes easy, then upper body, core and mobility work. |
| Wednesday | Recovery Run | 40 minutes | Run noticeably slower than your easy days. |
| Thursday | Medium Long Run, Strength and Mobility for Runners | 10 miles + 20 minutes | Build time on your feet without an effort finish, then support posture and control before the longest run. |
| Friday | Easy Run | 55 minutes | Keep the effort controlled before the race simulation. |
| Saturday | Long Run With Marathon Effort Finish | 20 miles | Close the final 5 miles at marathon effort. |
| Sunday | Rest or Light Movement | Rest or 25 minutes | Leave the day open for recovery or gentle movement. |
| Week total | 52 miles | The peak week and full race simulation before the taper. |
Every Week Opens With A Note Like This One
In Week 17, the coaching turns your race-morning routine into something already settled.
This is the peak of your plan and the closest rehearsal you will run. Twenty miles with a marathon-effort finish, and then it all gets easier.
Treat Saturday as a full simulation. Wake at the time you will wake on race day, eat what you will eat, wear what you will wear, carry what you will carry. The point is not to prove the fitness. It is to remove every remaining unknown so that on race day there is nothing left to work out.
Start slow. The race-effort section at the end of 20 miles is the whole session; the first 14 miles exist to set it up.
Focus this week on:
- Rehearsing race morning completely, including the timing of your last meal.
- Running the closing miles at controlled marathon effort, not faster.
- Planning nothing demanding for Sunday.
Everything comes down from here. The taper starts next week.
You receive 20 weekly notes like this, plus a separate coaching note on every run.
The 20 Weeks, Phase By Phase
| Weeks | Phase | Mileage | What It Does |
|---|---|---|---|
| 1 to 5 | Foundation | 31 to 41 miles | 6 runs a week with a Tuesday workout and 2 long runs, Thursday medium and Saturday long. Strides join Monday in Week 3 and Week 5 steps back to absorb the block. |
| 6 to 9 | Build | 35 to 44 miles | Tuesday cycles through threshold, fartlek and marathon effort work while the Thursday medium long run reaches 10 miles and Saturday reaches 12. Week 8 steps back a second time. |
| 10 to 14 | Race Effort | 37 to 48 miles | Marathon effort moves onto the long run in Week 10 and stays there. The Saturday run reaches 15 miles by Week 13, then Week 14 resets before the 3 peak weeks. |
| 15 to 17 | Peak | 49 to 52 miles | Long runs of 17, 18 and 20 miles, all finishing at marathon effort, alongside a marathon effort workout every Tuesday. Week 17 is the race simulation and the biggest week. |
| 18 to 19 | Taper | 31 to 41 miles | Mileage falls 21 miles across 2 weeks. Week 18's 14-mile long run keeps its effort finish, then Week 19 drops to 9 miles with a last marathon effort workout Tuesday. |
| 20 | Race Week | 18 miles + race | 4 easy runs Monday through Thursday, then a 20-minute shakeout Saturday and the marathon on Sunday. Friday is the only fully clear day, and nothing exceeds 45 minutes. |

Frequently Asked Questions
You are ready if 6 running days, an 8-mile weekly long run and a midweek workout are already normal training. Those are starting requirements, not targets to build toward after the plan begins. Week 1 gives you 6 runs, including a Tuesday fartlek, a 6-mile Thursday and an 8-mile Saturday.
The Beginner Marathon uses 4 easy runs and one weekly long run. This plan uses 6 runs, a Tuesday workout and 2 long runs, with marathon effort added to Saturday from Week 10. Both reach 20 miles, but the right choice comes from the weekly volume and workout load you already handle.
They divide the week’s sustained work so Saturday does not have to carry all of it. Thursday adds time on your feet without carrying an effort finish, then Saturday asks you to run long with some fatigue already present. That combination prepares you for the late stages of a marathon more specifically than one larger weekly run.
It is a 20-mile long run that closes with 5 miles at marathon effort. You also rehearse race morning completely, using the same wake time, food, clothing and kit planned for race day. The goal is to test the full routine while you still have time to correct anything that does not work.
Skip the missed run and continue with the next scheduled session. Do not stack runs, squeeze a long run into the wrong place, or turn a recovery week into a make-up week. Consistency across the 20 weeks of the plan beats being perfect for 2.
No. Every session is written on an RPE 1 to 10 effort scale. That means the plan works on hills, in heat, on tired legs and at any fitness level, and it keeps working as you get faster.
Pick your race, set your start date, and the plan builds backward from it. If the race moves, the plan moves. You keep it for life, which means the next build starts from something you already know works.
The Advanced Marathon adds more volume and a second weekly workout when you are ready for both. Repeating this plan is also a real option, because the durability built through the first cycle gives the same structure a different starting point the next time around.
