Los Angeles Marathon
training plan
An adaptive marathon plan for a net-downhill course on road, run in warm March conditions, built around the three things Los Angeles actually asks of you: a one-way course, heat and quad-wrecking descents. 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 a one-way course, heat or quad-wrecking descents.
On the ground, Los Angeles is a net-downhill course on road. It is usually held in March, when it is usually warm enough that the last hour costs more than the arithmetic says it should. So over a marathon, the cost is eccentric damage, banked early and paid for late, and the heat is a pacing tax you either trained for or pay in full on the day. There will be tens of thousands starters out there with you.

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 Los Angeles presents it rather than in a convenient loop from your front door.
Heat will cost you more than the course does
Warm, still air moves your heart rate up for no extra speed and turns a sensible pace into an unsustainable one. Fluid and sodium losses that seemed trivial in training become the reason you slow down.
Heat sessions in the last block, pacing set by effort rather than the number on your watch, and a fueling plan for Los Angeles Marathon that you rehearse in the long session.
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 Los Angeles where it decides your day.
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.
First come, first served
Places usually go on general sale and disappear on a timetable rather than a draw, so the date you can control is the one you start on. Sixteen weeks back from March puts the first week in late November.
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 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 sixteen-week block for a March race opens around late November, running November 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, warm 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 a one-way course, heat and quad-wrecking descents is what the rebuild puts back first.
- Weeks 1-6 November-January dark, cold and interrupted, so showing up matters more than intensity
- Weeks 7-10 January-February
- Weeks 11-16 · peak and taper February-March
Months assume Los Angeles keeps its usual March slot and that you take the full 16 weeks. Adaptlete builds from the date you enter.
A real week from a Los Angeles 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: downhill reps for the net-downhill profile, and a heat session for conditions that are usually warm. The key session itself is written for heat. For a March race, week 11 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 | 10 mi1H15 |
| WED | Zone 2, easy | Easy run + strides | 6 mi50' |
| THU | Zone 3, steady | Strength: single-leg & eccentrics | 45' |
| FRI | Zone 1, recovery | Recovery jog | 4 mi35' |
| SAT | Zone 4, threshold | Long run: at the hottest part of the day | 22 mi2H50 |
| SUN | Zone 1, recovery | Heat session: easy, in the warmest part of the day | 3 mi28' |
Something will go wrong.
That is the part we built for.
Nobody finishes a sixteen-week build without missing a week, and November 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 9
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 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 Los Angeles Marathon?
Sixteen weeks is the usual build for a marathon like Los Angeles, at 4-6 runs a week. Counted back from a March race that opens the block around late November and runs it November 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 a one-way course, heat and quad-wrecking descents first, and tells you plainly what it had to leave out.
When should I start training for Los Angeles Marathon?
Los Angeles is usually held in March, and the next edition an athlete could realistically build for is Spring 2027. Count back sixteen weeks from whatever date you enter and the block opens around late November, running November through to March. 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 first come, first served), and the training deadline is the one you control.
Is Los Angeles Marathon an easy course because it drops?
A net-downhill course on road, and in March it is usually warm enough that the last hour costs more than the arithmetic says it should. So the cost is eccentric damage, banked early and paid for late, and the heat is a pacing tax you either trained for or pay in full on the day. That combination is what the sixteen weeks are built around: a one-way course, heat and quad-wrecking descents. The marathon on its own would give you a completely different plan.
How do I keep a Los Angeles Marathon build going through the winter?
A sixteen-week block ending in March runs November 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.
How do I handle the heat at Los Angeles Marathon?
March in Los Angeles, CA is usually warm, and across a marathon that is a pacing problem before it is a toughness problem. The plan builds exposure gradually over the sixteen weeks instead of in race week (the peak week carries a heat session) and it checks your goal pace against what those conditions realistically allow. This is training guidance, not medical advice: if heat affects a condition you have, speak to a professional first.
Do I need hills to train for Los Angeles 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 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 a one-way course, heat and quad-wrecking descents, and none of the three gets dropped to make room for the others.
Is this an official Los Angeles Marathon training plan?
No. Adaptlete is an independent training-plan service with no affiliation to the organizers of Los Angeles 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.
