Mileage for Novice Marathon Runners

As a beginner to the marathon it is likely that your goal is to complete the distance.

If you are an experienced long distance runner, you might wish to consider yourself an intermediate marathon runner as some of the ideas here should be ones you are already familiar with (maybe you should read this to check!).

The first thing that should be stressed here is that much of your training for the marathon is going to be about time on your feet out running round the roads or parks getting your body used to the idea of running for 4, 5 or even 6 hours to complete the course. Depending on the terrain of your marathon it is also important to familiarise your body with running on this surface. So, for example, if your marathon is a road one, you should aim to complete a proportion of your training on harder surfaces in preparation.

You shouldn't concern yourself too much with the speed at which you do this, or even if you end up doing some of it at walking pace - but more about covering the miles in front of you.

To do this well you should build yourself a plan to follow as it is a great motivator to be able to tick off the sessions as you build towards the big day.

Also you must be prepared that you will feel aches and pains during this period of running training. This is perfectly normal, nothing to be alarmed by and most of the time fine to train through. However, if an ache or pain persists, getting significantly worse when you run, that is when your schedule needs to be flexible so you can reduce your mileage until the problem is resolved or seek advice from a physiotherapist or coach.

Building a Plan - Total Mileage

How far should I run each week?

This will depend on a number of factors including your current level of fitness, how long you have to go to race day, age, the amount of time you have available etc etc.

Generally, if you are of average age and fitness, you'll need to start your preparations at least 3-4 months in advance of the big day, and frankly the sooner you start the easier it will be.

Two goals that work quite well, although this isn't exclusively the case, are

  • Try not to increase your total mileage by more than 10% a week.
  • Try to build up to 45 miles in the week 3 weeks prior to the event.

If you work backwards from this you'll find that you need 16 weeks to move from 10 miles in the week to 45 miles, then adding on the 3 week taper after this to the race would mean you need to start training 19 weeks prior to the event.

Many coaches will also put lighter weeks into the schedule to allow the body to recover from the stresses of training, so in practice you'll ideally want a 6 month preparation period for your first marathon - if you currently run less than 10 miles in a week.



We believe 10 miles in a week is a good starting point for most averagely fit people - whether this be walking or running.

We would also recommend some form of cross training during the week on your days off from running to build your cardiovascular fitness. Anything from cycling to swimming are really good ways of improving your cardiovascular fitness without putting additional stress and strain through your joints. However, if this is making you feel too tired to complete your running schedule then abandon the cross training and instead prioritise the running!
