Getting Starting – Marathon Training Essentials
Here are some of the tried-and-true facts of marathon training:
How Long Does It Take To Train For a Marathon?
It typically takes between 4-6 months to train for a marathon, depending on your initial ability level and marathon goals.
The shortest marathon training program we recommend is 3 months, or 12 weeks.
How Fit Should I Be Before Beginning Marathon Training?
Ideally, you should have some recent running fitness – if you’ve run a half marathon in the past year or two you’re in good shape to progress to the full 26.2 miles (or 42.2 kilometers).
The less active you currently are, the more time you should spend easing yourself into running – if in doubt, we recommend aiming for a 10k or run a half marathon first!
How Long Should I Run Each Week?
Your weekly mileage will gradually build up throughout your marathon training – the starting mileage will be dictated by your ability level.
By the time your marathon training peaks, you’ll likely be running around 40 – 50 miles per week.
How Many Times Per Week Should I Run?
Most marathon training schedules have 4 or 5 running days per week, and one day for cross training. Some plans include only 3 running days per week.
Note that having a training partner or running with a group can really help your motivation!
Is Cross Training a Necessary Part of Marathon Training?
Yes – keeping the body strong and flexible helps counteract some of the negative effects of running, helps you avoid injury, and become a stronger and more economical runner.
Each of our marathon training programs features one day for cross training.
Setting Marathon Goals
We recommend that you choose a marathon goal early on in your training program – your goal can influence your training strategy.
Example marathon goals include ‘just finishing‘ , or finishing within a certain time i.e. running a sub 4-hr marathon.

How Long Should My Longest Long Run Be?
Long runs are performed weekly to increase your endurance and maximum distance – we advise a longest long run of 20 – 22 miles, depending on your training schedule.
Rookie runners should peak at 20 miles.
Anything more than this risks burnout and injury more than it contributes to your fitness.
Is a Marathon Training Plan Necessary?
Having a solid marathon training program to follow guides you through your training – it gradually increases your mileage, balances intensity with rest, and gets you race-ready as economically as possible!

Marathon Training Run Types Explained
Many running rookies wrongly believe that training for a marathon simply means booking dozens of miles – but this isn’t the full picture.
Successful marathon runners mix up their training with different types of training runs:
Classic Training Runs
Regular training runs are those runs typically done 2-3 times per week of training, usually after work or early in the morning. They’re the most common form of training on a marathon training plan.
They’re medium-length runs of 3 – 8 miles, done at a regular pace (marathon pace or slower).
Long runs are done once per week, in order to build endurance and cover long distances.
Their mileage should very gradually increase until it peaks at 20 – 22 miles. They should normally be done at a slow, comfortable pace.
Note that speed work is not necessary for beginner runners, only those trying to aim for a specific marathon time.
Cross-training is not essential, but is always recommended – it’s an awesome tool for improving running economy and power and avoiding injury.
Marathon Nutrition and Hydration
Getting your nutrition and hydration right as you make the step up to marathons is an essential part of your training progress.
As you increase the distance you’re running, it’s important to fuel as you run – in other words, replenish those carbohydrate stores which you’re depleting. Otherwise, you could quite easily hit the wall, or bonk.
Remember to fuel 45-60 minutes before you go running, and continue to fuel for any run that is over an hour. Whether it’s a sports drink, energy gel, or trail mix – it’s better to consume small but regular portions.
The same goes for hydration – for any run of over 45 minutes, consider rehydrating during the run.
Take care not to overhydrate, however – simply drink enough to quench your thirst. Small and regular sips is the easiest way to go.
