Beginner Marathon Training Plan

Written by Andrew Taylor. USATF Level 1 Coach. Coaching runners since 2010.

Your first marathon changes the way you name yourself.

You have covered a half marathon or a 10K, and now you are looking at 26.2 miles. The question is whether your current running can carry you through a distance you have never attempted.

Training for that asks for 5 months of consistent work. The long run needs enough weeks for each new distance to land on a body that has already absorbed the one before it.

Easy running lets you build endurance without turning each week into something you need to recover from. That repeatability is what carries a first marathon build across 5 months.

Before You Start

Consistently run 15 to 20 miles a week, 4 days per week for 30 to 35 minutes on regular runs and 6 miles on a long run. No speed work experience needed. Prior 10K or half marathon experience recommended.

Twenty Miles Is Enough Rehearsal

The last long run is a rehearsal for time on your feet, not a rehearsal of the marathon. Twenty miles at an easy effort teaches your body what 3 or 4 hours of continuous running feels like. For a first marathon, removing some of the fear around sustained movement matters more than forcing a race-effort finish.

Marathon effort belongs on shorter long runs. You still have enough left afterward to absorb the faster finish and carry its benefit forward.

Adding the same finish to the 20-mile run would leave you recovering when the taper needs to begin. The remaining 6.2 miles come from 20 weeks of accumulated easy running and the freshness you carry into race day.

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.

A Real Week From The Plan

Week 17 asks for your longest run after every earlier block has prepared you to absorb it.

Day Session Time What It Asks For
Monday Recovery Run 60 minutes Keep the effort lower than your other weekday runs.
Tuesday Strength and Mobility for Runners 20 minutes Complete the final strength and mobility session before the taper.
Wednesday Easy Run Plus Pickups 60 minutes Run easy, adding 5 relaxed pickups in the second half.
Thursday Cross Training 30 minutes Choose low-impact work or take the day off.
Friday Easy Run 60 minutes Hold a conversational effort throughout.
Saturday Long Run 20 miles Run the longest distance in the plan entirely easy.
Sunday Rest Day Full rest Leave the day open for recovery.
Week total 39 miles The peak week and the final long run before the taper.

The week after a 20-mile Saturday is decided by what you do with Sunday, which is why the plan leaves it completely open.

Every Week Opens With A Note Like This One

The Week 17 note keeps the longest run focused on endurance instead of proof.

This is it, the biggest week of your plan and your last long run. Twenty miles on Saturday, and then everything gets easier.

The 20 miler carries no race-effort finish, and that is deliberate. At this distance, on a 4-day plan, time on your feet is the whole ask. Adding a hard finish would cost you more in recovery than it would return in fitness, and Week 18 needs you intact.

Run it at a comfortable, conversational effort throughout. You are not proving anything today. You are teaching your body what 3 or 4 hours of continuous running feels like, and taking the fear out of the distance.

Focus this week on:

  • Starting slower than you think you should, and staying there.
  • Fueling from the first 30 minutes, not from when you feel low.
  • Walking through aid stops if you need to. Race day may well include some.
  • 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 17 to 21 miles 4 runs a week, all easy, with the long run growing from 6 to 9 miles. Pickups join Wednesday in Week 3 and Week 5 steps back before the first real build.
6 to 11 Build 20 to 28 miles The long run climbs to 13 miles across 2 blocks, with recovery weeks at 8 and 11. Everything is still easy running, which is what lets 4 days a week carry it.
12 to 14 Race Effort 25 to 32 miles Marathon effort arrives on the long run in Week 12 and stays through Week 13's 15 miles. Week 14 steps back, the last down week before the 3 biggest of the plan.
15 to 17 Peak 33 to 39 miles Long runs of 16, 18 and 20 miles on 3 straight weeks. The 16 and 18 finish at marathon effort, and the 20 is run entirely easy, because distance is its only job.
18 to 19 Taper 20 to 26 miles Mileage falls 19 miles across 2 weeks. Week 18's 12-mile long run keeps a marathon effort finish, then Week 19 drops to 8 miles and everything goes easy.
20 Race Week 8 miles + race A recovery run Monday, an easy run Wednesday and a 20-minute shakeout Friday, then the marathon on Sunday. No session in the week is longer than 30 minutes.

What You Get Inside Training Plan

Frequently Asked Questions

You are ready if you already run 4 days a week and feel comfortable completing a 6-mile long run. You do not need marathon experience, but that starting frequency and distance should already be part of your running. Week 1 assumes your body knows what consistent running feels like before the long build begins.

Yes, 4 days a week is enough for a first marathon. Every run stays easy or recovery effort, so the schedule remains repeatable across 20 weeks while the long run grows. Finishing the full plan matters more than choosing a schedule with more running days than you can consistently complete for 5 months.

Yes. Planned walking can help you control effort, take in fuel, handle hills, and move through aid stations without rushing. Many marathon finishers use those breaks deliberately on race day. Walking is a pacing and fueling choice at this distance, not evidence that the run has gone wrong.

Yes, the Tuesday strength session is part of the plan. Each session lasts 15 to 20 minutes and supports the running without adding another run day. When a week becomes crowded, continuing with the scheduled runs matters more than stacking missed strength work later.

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 Intermediate Marathon adds harder training when you want to prepare for a second marathon differently. You can also repeat this plan from the fitness left by your first build, using the same 4-day structure with a starting point your body already recognizes.
