Lisbon Half Marathon
training plan
An adaptive half marathon plan for a net-downhill course on road, run in temperate March conditions, built around the three things Lisbon actually asks of you: quad-wrecking descents, bridges and camber and a one-way course. Twelve 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 12-week half marathon plan gets you to the start line. It has no idea about quad-wrecking descents, bridges and camber or a one-way course.
On the ground, Lisbon is a net-downhill course on road. It is usually held in March, when conditions are usually mild, which quietly removes the weather from your list of excuses. So over a half marathon, the cost is eccentric damage, banked early and paid for late, and the weather is unlikely to be the thing you end up blaming. There will be tens of thousands starters out there with you.

The descending is free speed you pay for later
Losing height early feels like a gift. It is eccentric loading, and the bill arrives with about a quarter of the race left, as quads that stop answering. Most blow-ups on a course like this come from tissue damage. Fitness is rarely the cause.
Descending reps from the first block, and long sessions that put the downhill early. Your legs meet the damage in training, well before the point of Lisbon where it decides your day.
The only hills are bridges, and the road tilts
A city course with no real climbs still has bridge ramps and a cambered road surface. The camber quietly loads one leg more than the other for hours, and the bridges arrive as short, steep efforts at exactly the wrong moment.
Short steep repeats sized like the ramps rather than like hills, plus single-leg strength for the asymmetric loading a cambered road puts through your hips over the length of Lisbon Half Marathon.
Nothing about the day is symmetrical
A point-to-point route means an early transfer, a start far from your bed, and a profile that never returns to where it began. Logistics eat into the night before, and the course gives no second chance at any section.
Race-week guidance built around an early, disrupted morning, and long sessions that rehearse the profile in the order Lisbon presents it rather than in a convenient loop from your front door.
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.
Open entry
Entry usually stays open close to the day, which sounds relaxed and is exactly why so many people start their build six weeks out. Twelve weeks back from March puts the first week in late December.
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 a downhill start makes everybody around you faster than they can hold. Over a half 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 downhill reps on it, months before March.
You will be training through the northern winter
Work backwards and a twelve-week block for a March race opens around late December, running December through to March. That is the northern winter, and it is the half of the job most plans never mention. Most of your long sessions will start or finish in the dark, in weather that makes the warm-up longer than the session. Ice takes the pace out of your hands, a chest infection goes round in week six, and the treadmill stops being a punishment and starts being a tool. And the last block lands in March, with net-downhill ground, temperate conditions and a large field waiting at the end of it.
So the plan swaps outdoor quality for treadmill or turbo equivalents by effort rather than pace when the ground is unrunnable, and treats a week lost to illness as a rebuild rather than a hole to run through. Whatever the season takes out of two weeks, the work for quad-wrecking descents, bridges and camber and a one-way course is what the rebuild puts back first.
- Weeks 1-5 December-January dark, cold and interrupted, so showing up matters more than intensity
- Weeks 6-7 January-February
- Weeks 8-12 · peak and taper February-March the weather turns mid-block; the ramp holds steady anyway
Months assume Lisbon keeps its usual March slot and that you take the full 12 weeks. Adaptlete builds from the date you enter.
A real week from a Lisbon build
This is the shape of the biggest week in 12: 4-5 runs a week, 5H 18M of training, and one session that matters more than the rest. Two of them are here because of this course and not the distance: downhill reps for the net-downhill profile, and a race-hour rehearsal for conditions that are usually temperate. The key session itself is written for quad-wrecking descents. For a March race, week 8 lands in February. 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 | Downhill reps: 8 × 90 s of controlled descending | 11 km55' |
| WED | Zone 2, easy | Easy run | 8 km42' |
| THU | Zone 3, steady | Strength: hips & calves | 40' |
| FRI | Zone 1, recovery | Race-hour rehearsal: moved to the hour the race starts | 6 km34' |
| SAT | Zone 3, steady | Long run: descents loaded into the first half | 23 km1H45 |
| SUN | Zone 2, easy | Easy run + strides | 8 km42' |
Something will go wrong.
That is the part we built for.
Nobody finishes a twelve-week build without missing a week, and December through to March 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 7
Hotel treadmill, nothing else? Those days get rewritten around it.
Flu in January
The block rebuilds and ramps you back. Nothing is deleted.
A niggle at week 8
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 Lisbon Half Marathon?
Twelve weeks is the usual build for a half marathon like Lisbon, at 4-5 runs a week. Counted back from a March race that opens the block around late December and runs it December through to March. 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 quad-wrecking descents, bridges and camber and a one-way course first, and tells you plainly what it had to leave out.
When should I start training for Lisbon Half Marathon?
Lisbon is usually held in March, and the next edition an athlete could realistically build for is Spring 2027. Count back twelve weeks from whatever date you enter and the block opens around late December, running December through to March. Adaptlete builds backwards from your date, so the whole half marathon plan lines itself up the moment the date is confirmed. Entry runs on a separate clock (places here are on open entry), and the training deadline is the one you control.
Is Lisbon Half Marathon an easy course because it drops?
A net-downhill course on road, and in March conditions are usually mild, which quietly removes the weather from your list of excuses. So the cost is eccentric damage, banked early and paid for late, and the weather is unlikely to be the thing you end up blaming. That combination is what the twelve weeks are built around: quad-wrecking descents, bridges and camber and a one-way course. The half marathon on its own would give you a completely different plan.
How do I keep a Lisbon Half Marathon build going through the winter?
A twelve-week block ending in March runs December through to March, which is the northern winter. Most of the long sessions start or finish in the dark, ice takes the pace out of your hands, and something goes around the office in the middle third. The plan swaps outdoor quality for treadmill or turbo work by effort rather than pace when the ground is unrunnable, and treats a week lost to illness as a rebuild instead of a hole to run through.
Do I need hills to train for Lisbon Half Marathon?
We publish no climb total for this course, because we hold none we would stand behind. What we can say is that it is net-downhill ground. That is net-downhill ground on road, over a half marathon, and it is trainable without moving house. The peak week carries downhill reps and loads the long session the way the course does. Train somewhere flat and the plan substitutes sustained-effort and eccentric work that loads the same tissue, and tells you it has done so. It is one of quad-wrecking descents, bridges and camber and a one-way course, and none of the three gets dropped to make room for the others.
Does the surface at Lisbon Half Marathon need its own training?
Yes, and it is the part people leave until race week. 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. Over a half marathon on net-downhill ground the rough sections cost more than their length suggests, so the twelve-week block puts uneven footing into the long sessions deliberately rather than hoping March is kind.
Is this an official Lisbon Half Marathon training plan?
No. Adaptlete is an independent training-plan service with no affiliation to the organizers of Lisbon Half 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.
