Your first marathon is a HUGE accomplishment, and you deserve a medal for all the hard work it took to get there.
There is no one-size-fits-all training schedule for marathon running. You will have to find the right plan that works for you, but here are some general guidelines to get you started:
Create a Schedule
It’s important to stick to your training schedule. People who don’t follow their plan end up getting injured or quitting halfway through the race.
Minimum Exercise to Aim
You should be able to exercise four to five times a week, and at least three days of that should be long runs. Some people like shorter long runs, while others like doing longer ones. Experiment with each length and see what works best for you!
A good way to start out your training is by doing a preseason long run of 20 miles.
