Dublin Marathon
training plan
An adaptive marathon plan for rolling ground on road, run in cool October conditions, built around the three things Dublin actually asks of you: climbing in the last third, ground that never flattens and exposed wind. Sixteen weeks written two at a time, from what you actually did in the two weeks before, and rewritten the moment you travel, get ill or something starts hurting.
This page describes the race and what its course, climate and date ask of a build. On Pro, the plan itself is written for you, from your experience, your weekly hours and your date, so two athletes entered in this race get different plans.

Three demands, three answers
A generic 16-week marathon plan gets you to the start line. It has no idea about climbing in the last third, ground that never flattens or exposed wind.
On the ground, Dublin is rolling ground on road. It is usually held in October, when conditions are usually cool, which is good racing weather but means a cold twenty minutes standing about beforehand. So over a marathon, the cost is effort drifting upward over hours without you noticing, and the weather is more likely to help you than to hurt you. There will be tens of thousands starters out there with you.

The climbing arrives where the race is decided
The hills do not sit in the first hour where you have legs for them. They land in the last third, in the window that decides the whole day. Fresh-legged hill repeats teach you almost nothing about that.
Climbing placed at the back of long sessions, at roughly the same fraction of the distance Dublin puts it. Tired-legged climbing is a separate skill and it is trainable.
It never flattens out and it never really climbs
A course of constant small rises never lets you settle into one rhythm. Even pacing is impossible, effort drifts upward without you noticing, and the cost shows up as a split that falls apart late.
Sessions run on rolling terrain to fixed effort rather than fixed pace, so you learn what Dublin costs at the top of each rise instead of chasing a number that the profile will not let you hold.
The wind sets your pace for you
Exposed sections turn a steady effort into a fight. Chasing a pace into a headwind spends energy you will want later; sitting up in a tailwind gives away free speed.
Sessions run to effort in exposed conditions, so on Dublin you already know what the right effort feels like when the number on the watch is lying to you.
Getting in, and getting to the line
Adaptlete has no involvement in entry, allocation or ballots for any race. This is what the format asks of your planning.
Ballot
Places usually go by ballot, which makes the honest sequence place first, plan second. If the draw goes against you, the same block moves to another race without being rewritten. Sixteen weeks back from October puts the first week in late June.
Large field
A large field means a start pen, a gun time that is not your chip time, and a first mile you do not control, and on rolling ground the bunching happens on every rise, all day. Over a marathon, that is a long time to be running somebody else's race.
Road
Road, which is the easy part to train for and the easy part to get wrong: the same shoes, the same socks and the same drink you intend to race in, used often enough that race morning contains no first times. The peak week puts a rolling tempo on it, months before October.
You will be training through the northern summer
Work backwards and a sixteen-week block for an October race opens around late June, running June through to October. That is the northern summer, and it is the half of the job most plans never mention. Long sessions get pushed earlier and earlier to dodge the heat, the calendar fills up with weekends away, and two weeks of vacation land somewhere in the middle of the block whether the plan wants them or not. And the last block lands in October, with rolling ground, cool conditions and a large field waiting at the end of it.
So the plan expects the interruption instead of pretending it will not happen: sessions move to the cool hours, and two weeks away is rewritten around what you will actually have, whether that is a hotel gym, a rental bike, or a pair of shoes and nothing else. Whatever the season takes out of two weeks, the work for climbing in the last third, ground that never flattens and exposed wind is what the rebuild puts back first.
- Weeks 1-6 June-August early starts and heat; the long sessions move to the cool hours
- Weeks 7-10 August-September
- Weeks 11-16 · peak and taper September-October the light goes; the sessions that need it come first
Months assume Dublin keeps its usual October slot and that you take the full 16 weeks. Adaptlete builds from the date you enter.
A real week from a Dublin build
This is the shape of the biggest week in 16: 4-6 runs a week, 6H 43M of training, and one session that matters more than the rest. Two of them are here because of this course and not the distance: a rolling tempo for the rolling profile, and a cold-start rehearsal for conditions that are usually cool. The key session itself is written for climbing in the last third. For an October race, week 11 lands in September. Your version is written from your hours, your history and how far out you are.
- Every session says what it is for, in plain language
- Intensity you can scan down the week without reading
- Move any session to any day without breaking the block
| Day | Intensity | Session | Distance and duration |
|---|---|---|---|
| MON | Rest | Rest | |
| TUE | Zone 4, threshold | Rolling tempo: 30 min to effort, over the top of every rise | 16 km1H15 |
| WED | Zone 2, easy | Easy run + strides | 10 km50' |
| THU | Zone 3, steady | Strength: single-leg & eccentrics | 45' |
| FRI | Zone 1, recovery | Recovery jog | 6 km35' |
| SAT | Zone 4, threshold | Long run: climbing loaded into the last third | 35 km2H50 |
| SUN | Zone 1, recovery | Cold-start rehearsal: race effort inside the first ten minutes, from cold | 5 km28' |
Something will go wrong.
That is the part we built for.
Nobody finishes a sixteen-week build without missing a week, and June through to October is a long time to stay lucky. The plans that fail are the ones that carry on as if nothing happened.
A work trip in week 9
Hotel treadmill, nothing else? Those days get rewritten around it.
Flu in August
The block rebuilds and ramps you back. Nothing is deleted.
A niggle at week 12
Loading comes off it, the rest of your week stays. And go see someone.
Questions people actually search
How many weeks do I need to train for Dublin Marathon?
Sixteen weeks is the usual build for a marathon like Dublin, at 4-6 runs a week. Counted back from an October race that opens the block around late June and runs it June through to October. Coming from a lower base, give yourself longer. With fewer weeks than that the plan compresses. It builds what it can from where you are, protects the work for climbing in the last third, ground that never flattens and exposed wind first, and tells you plainly what it had to leave out.
When should I start training for Dublin Marathon?
Dublin is usually held in October, and the next edition an athlete could realistically build for is October 2027. Count back sixteen weeks from whatever date you enter and the block opens around late June, running June through to October. Adaptlete builds backwards from your date, so the whole marathon plan lines itself up the moment the date is confirmed. Entry runs on a separate clock (places here are allocated by ballot), and the training deadline is the one you control.
What makes Dublin Marathon harder than its profile looks?
Rolling ground on road, and in October conditions are usually cool, which is good racing weather but means a cold twenty minutes standing about beforehand. So the cost is effort drifting upward over hours without you noticing, and the weather is more likely to help you than to hurt you. That combination is what the sixteen weeks are built around: climbing in the last third, ground that never flattens and exposed wind. The marathon on its own would give you a completely different plan.
How do I train through the summer for Dublin Marathon?
A sixteen-week block ending in October runs June through to October, which is the northern summer. Expect long sessions pushed into the cool hours, a diary full of weekends away, and a vacation landing somewhere in the middle whether the plan wants it or not. Tell the app what you will actually have (a hotel gym, a rental bike, or shoes and nothing else) and the next two weeks are rewritten around it instead of written off.
What if I do not get a place at Dublin Marathon?
Places usually go by ballot, which makes the honest sequence place first, plan second. If the draw goes against you, the same block moves to another race without being rewritten. The sixteen-week marathon block is written for rolling road and tens of thousands starters, whatever the paperwork says, so if the draw goes against you it moves to another October-ish target and rebuilds around the new date. Enter your date in the app once you hold a place; October 2027 is the edition this page is written against.
How should I practice fueling for Dublin Marathon?
In the long session, every week, with the food and drink you actually intend to use. Race day should never be the first time. A marathon on rolling road takes long enough that fueling is a limiter in its own right, and conditions are usually cool, which is good racing weather but means a cold twenty minutes standing about beforehand, which changes what goes down. The plan puts the rehearsal in the sixteen-week block and keeps it there when the rest of your two weeks gets rewritten. General training guidance, not nutrition or medical advice.
Is this an official Dublin Marathon training plan?
No. Adaptlete is an independent training-plan service with no affiliation to the organizers of Dublin Marathon, and none is implied. We name the race because the plan is built around what its course, its format and its date ask of you.
