Lungs burning, legs heavy, feet aching. And that was after the first mile. I kept checking my heart rate and pace. One was high the other low. So I kept lying to myself and said I would stop. Soon.

That was ten years ago.

At the time I didn’t see it. The discipline of getting up, lacing my shoes, and stepping outside in Missouri’s brutal summer humidity, thank you cornfields, changed me. I found strength and courage, confidence in my own abilities. It impacted everything.

Discipline works your mind. You push yourself out of bed on the hottest of mornings, hours before the sun crests the horizon, when your own body is desiring more sleep. Months later your body is still fighting you, and some days it wins. But for the most part, you don’t let it win. You go, not thinking about anything else except the next mile.

But when discipline hits your heart? That’s something I learned. No one told me that would happen. Discipline never removed the fear. It changed how I carried it. My physical heart made its adjustments over the miles. My emotional heart got stronger too, recognizing fear is like the summer heat, this too shall pass. So keep moving, one foot in front of the other.

When discipline reaches your will? That’s when things really start happening. Once I thought it would be impossible to run 13.1 miles. Today, that’s a half marathon, doable in under three hours. Impossible is attainable through training. Fuel. Hydration. And mental toughness. Pushing yourself beyond your physical capacity means being tough where it counts.

Training continues for me, slow but doable. 13:56 pace, slower than I’ve ever run before. And I smiled knowing I was one of those runners who will keep moving, no matter what, because I love it. The pace will get faster. Time on feet is my mantra for now.

Possible comes after discipline. Easy? Not hardly. Possible comes when you recognize difficulty will stay put. You, on the other hand, are strong enough to endure, push through, and fight. You stand inside yourself knowing you can do this.

I changed. It wasn’t the road or the mileage. Internally I knew I had the endurance to keep pushing.

Pay attention. That’s what discipline is. Listen to your body. Because excellence isn’t a short sprint burst of effort. It’s the compound interest of a thousand ordinary mornings where you show up and do one small thing right. Then you keep doing it. Over and over.

The miles don’t scare me. I’ve done this enough to know my limits, what I can and can’t handle. Let the repetition and discipline do its thing.

Hit the mark.

Finish the race.

Then get up and do it all over again.
