Marathons are all the rage these days, but the demanding distance isn’t for everyone. Here are some things to consider.

Marathon participation around the world is booming in recent years. Given the numbers supported by data, it’s obvious that running the vaunted 26.2-mile distance is quickly becoming the de facto goal for many beginner runners.

Likewise, experienced runners are increasingly magnetized to the popular distance as an opportunity to compare personal bests with their running buddies. When it seems like everyone is training for a marathon, the pressure to run one yourself can seem daunting.

However, is it possible that training for and racing a marathon might not be in your best interest?

Let’s take a look at why temporarily reconsidering your marathon racing plans might pay off for you in the long run.

Not Enough Training Background

The first and perhaps most obvious reason you might not want to run a marathon is a lack of training or experienced running background. The marathon is an arduous event and requires a dedicated training block of at least two months for serious runners and four months or more for newer runners. Remember, the more time you give yourself to train for your goal race, the better your chances of success.

More importantly, training for a marathon when you don’t have the requisite running background is a surefire way to get injured or find yourself disenchanted with running if you’re new to the sport. In my experience as a coach, I’ve found that beginners need to be able to average at least 40 miles per week for 5-6 weeks to increase the chance that they will have a good race experience. This means that you need to be able to comfortably run 30-35 miles per week before you begin training for a marathon.

If you’re not at this number, it doesn’t mean you can never train for a marathon. Rather, you should focus on slowly building your training tolerance and mileage background. Otherwise, you’ll likely struggle to increase the length of your long runs, as well your weekly mileage, enough to be adequately prepared on race day.

When runners neglect this advice, they often find themselves in a vicious injury cycle that is tough to break free from. First, the sharp initial increase in training results in a small injury that sets them back a week. To make up for missed time, they push the envelope to get back on track and develop another small injury. The cycle repeats itself throughout the entire training segment until race week, when a runner realizes has has not put together a solid, uninterrupted month of training since they started.

The last thing anyone wants on marathon race day is to have a bad experience and to suffer through the course. Even if your goal is only to finish, make sure you have the necessary running background to start marathon training on the right foot to stay injury-free and to have a good race.
