Your marathon training will involve a large amount of endurance work where you need to be "on your feet" for significant amounts of time to ensure
your body can "do the time".
You will need to take your current level of fitness into account when starting to build any schedule and gradually increase the
distance you are covering.
Debut Marathon Schedule
A simple schedule can be put together for beginners whereby you aim to run 3-4 times a week (ideally 4) with a gradual increase
(no more than 10% in total distance, or longest run) each week. The idea would be to build up to a peak of about 40 miles a week
and a single longest run of 20 miles - about 4 weeks prior to the race.
You would then look to reduce this distance by about 25% a week so you are fully prepared and rested for the race day.
To reach this kind of high mileage can take some time if you are unfit at the start, so we would recommend beginners try to start
preparing 4-6 months in advance of race day.
