Have you ever tried deeply concentrating for two and a half hours without a break?

It’s hard.

Have you ever tried deeply concentrating while running as fast as you can for 26.2 miles in the same amount of time without a break?

It’s hard.

It’s hard focusing when we’re tired.

It’s hard to stay alert and pay attention for long periods of time.

It’s mentally depleting.

It takes a lot of mental energy.

The more tired we get the harder it gets.

The more tired we get the more we have to exert ourselves.

It requires more energy and effort as we go.

When it comes to marathon running, endurance sports, and other physical activities, we often talk about the physical side.

We don’t talk nearly enough about the mental side.

The ability to focus and concentrate when tired is a skill.

It’s a teachable skill.

It can be trained and developed.

We have to practice it.

We need to build mental endurance and strength just as much as physical.

Don’t forget to train the mind.

It’s also important.

So the next time you’re at the end of that workout or long run, really pay attention and focus on what you’re doing.
