There is a secret about training to finish a marathon that no one really tells you.
Even though it’s hiding in plain sight behind a simple Google search, for the most part no one comes right out and says it.
I’m going to do you a solid and spell it out for you:
If you can run three miles, you can train to finish a marathon.
If you Google ‘marathon training for beginners’ or ‘first time marathoner’, you’ll find a ton of really good training programs to sift through. As you click-through all the first-time marathon plans, you’ll probably notice two things. The first thing is that all of them offer up a disclaimer of sorts telling you to spend at least a few weeks working up to the first week’s training distances. The second thing you’ll likely notice is that most of the first couple of weeks in these plans include several three mile runs.
Essentially what they’re telling you is that before you graduate to training to finish a marathon, you should be able to run three miles with ease.
