How to train for a marathon

To answer this question, we have enlisted the help of SAYSKY athlete and running coach Sebastian Reinwand. He's one of the fastest runners in Germany, with a marathon PB of 2:15:27 and many years of experience in running and coaching.

Although, we do acknowledge that marathon training can be approached from many angles, depending on the specific goal or target time, we feel that Sebastian's advice is still a very good starting point for a lot of runners out there.

Read the interview below for a handful of great tips on how to train for a marathon.

Marathon Training Tips

How many weeks before a marathon should you actually start the training? 

A normal marathon preparation takes 12 weeks, but these 12 weeks are already specific marathon training. I suggest to do 3-5 weeks of basics training before that, to be prepared for serious stuff - especially the long runs. 

What is your best tips for the marathon training? Should one consider tempo runs, long runs etc.?

The key to success is doing progressive long runs between 32-38km. Such intensive long runs have the same impact as a tempo session. That's why I usually only do one additional tempo/interval training (sub race pace) on Wednesdays and and then the long runs on Sundays. 

How much mileage should a person run each week? And how many days per week should you run?

How much mileage you have to run depends on your goal and talent. But, what I can say is that you should run at least 4 times per week and around 80k to prepare seriously for a marathon and avoid injuries. It's important that your bio-mechanical system (all the muscles and tendons) can to adapt to running 42 kilometres straight.

What is your absolute best advice for running a marathon? And do you have any do’s and dont's?

Fuel carbs from the beginning and every 5k to keep the engine running. Also, the worst thing you can do is going out too fast. So, stay patient - you have 42k to go! Moreover, go for a negative split if possible. Run the second half faster and with the proper fuel to put you on a runner's high after 35k, instead of meeting the man with the hammer.

Should one consider tapering?

Every one should reduce the weekly mileage for the last three weeks of the preparation. Your body will rest now and likes to do some race pace reps, but always make sure to be fully recovered, both before and after. I suggest to race a hard 10k two weeks out. That puts your body and mind into race/suffer mode and will make marathon pace feel so much easier when the gun goes off.

What should the relation be between your training pace and your race pace?

You should be able to average your last long run three weeks out in 90-95% of your goal race pace, e.g. a sub3h should do:

35k: 10k/4:55 + 10k/4:40 + 10k/4:30 + 5k/4:12
