An introduction to training for a 2018 marathon

Whether you’re running in Boston or London, Paris or Rome, Sydney or Stockholm, Wiggle is here to help you fulfil your dream of running a marathon this year.

The 26.2 miles will likely be the hardest of your life. Completing the course is a significant feat of athleticism and mental fortitude accomplished by fewer than 1% of the population.

For those that manage it, it’s an unforgettable event and a source of personal pride for the rest of their lives.


What is the Wiggle Marathon Training Guide 2018?

Over the next 16 weeks, Wiggle will be providing a detailed series of training tips, programmes, support, and information to help you turn your running ambition into reality.

Over the coming weeks, we’ll look in detail at different training techniques and preparation priorities to help you reenact the historic journey of Pheidippides.

We’ll also discuss many of the tools that can help you along the way, how to avoid injury, how to recover, and provide some important motivation to keep you focused and training regularly.


Let’s get started

Running a marathon is a long-term commitment and requires a detailed plan to which you are prepared to stick.

If this is your first marathon, it’s important to note that the goal of the race is not to achieve a specific time, but simply to finish.

It will take a typical runner around four months to prepare for the full 26.2 miles, adding the extra distance gradually with the aim of reaching your peak on race day. 


Your training schedule

The below 16-week plan below should give you a general idea of how to structure your training, gradually adding miles every week and building your stamina and aerobic capacity over the four-months.

You’ll see the number of miles or metres you should aim to run on each of the days. Notice how the distances get longer with each week before tapering down before race day to help you peak for the big event. The below plan will not be perfect for everyone, so listen to your body and make the necessary adjustments so that your training is specific to you.

*M = miles | m = metres

Using this as a template for your regime, you can begin to build out your plan. But remember, there is more to marathon training than just smashing miles, there’s also hill and interval training, long runs and speed work, as well as race strategies to think about.

Over the coming weeks, Wiggle’s Marathon Training Guide series will explore all these training techniques and approaches to help you create a complete programme you can tailor exactly to your needs.


Week 1 – what equipment do you need?

This is the beginning of a long but ultimately fulfilling journey, and if you're relatively new to running, or returning to the discipline, you’ll need just a few items to get you started.

Running shoes

If you stick to the training schedule above, you’ll be running around 300 miles over the next four months, so you need a decent pair of dedicated running shoes to pound those pavements.

The last thing you want is to pick up an injury, as this will add pressure to the rest of your plan and hamper your efforts. This means finding the right shoes is an important investment to ensure your training stays on schedule and that your delicate joints and ligaments are protected.

Before buying, it’s important to note if you have any pronation issues in order to find the right shoe that fits your run style. Wiggle has a complete guide to finding out if you over or under-pronate in your stride, or if you’re a neutral runner, and how to buy the most suitable footwear.

Running socks

The value of a good running sock is in the reduction in blisters and bleeding suffered during your runs, which will provide significant benefits to not only your running style, but your endurance and motivation. Running long miles is hard enough without the burning, stinging pains of abrasions on your feet.

There are also options for compression, which many runners find beneficial.

A good running sock can work wonders in this regard and are relatively cheap, so make sure you pick up a pair.

Running clothing

Training for a marathon means a lot of hours spent out on the road, so having some quality running gear will contribute immensely to your comfort.

Specialist run attire comes with a range of technologies and benefits to keep your temperature moderate, limit chaffing, and provide breathability to help you push that little bit further.

Your needs will change from winter to your eventual run during early summer, so if you’re starting in the first week of January, then getting some base layers and a good winter jacket is an important step.

You may also need a hat and gloves for when the temperatures approach zero, along with winter tights or trousers.

These items will keep you warm and simultaneously wick away sweat from the surface of your skin, stopping you from becoming clammy and uncomfortable.

Female runners may also benefit from a supportive training bra.

Tracking your progress

Measuring your outcomes will help you extract the maximum value from your careful planning and preparation, which is why many runners use GPS tracking systems to help visualise and monitor their progress.

One option is to use a running or training smartphone app like Strava. Alternatively, try a dedicated GPS run computer such as the Suunto Ambit 3 Vertical (HR) or the Garmin Vivofit 3 Activity Tracker.

These can be used to create precise routes as your run distance increases, allowing you to check your times against set goals.

Another increasingly popular choice is a heartrate monitor, such as the Wahoo TICKR X Heart Rate Monitor, which will also give you a precise measure of your increasing fitness during your training.

Not only will you need a lot of running fuel to drive those feet forward, your body will also require big helpings of protein to repair damaged ligaments and muscles.

Beware of rumours that you need to carb-load at every opportunity, however. What your body needs most of all is a varied and balanced diet, filled with nutritious foods.

Competitive runners can, however, benefit from supplements, such as protein sources and energy gels, which are used to provide a much-needed source of fuel while on your run.
