Can You Train for an Ironman on Keto? I’m Trying

Training is one thing — but fixing my diet is just as important.
Like most runners, I started out fully fueled by carbs. For my first marathon, it was all sugar, bread, and chocolate. I love chocolate. I added sugar to my café latte and thought nothing of it.

Training helped me lose weight — at first. But eventually, I hit a plateau. More intensity didn’t help. The scale stayed still. And on longer distances, the real problem showed up: I kept hitting the wall. No matter how many carbs I stuffed in — energy would crash. Every time.

I wanted something better.

That’s when I started reading about low carb and keto for endurance athletes. I did my first fast, started shifting my nutrition, and felt something change. That’s also when the first idea of signing up for an Ironman came to me.

Then I ruined it.

I lost my rhythm. Lost the discipline. Fell back into old habits.
Now it’s time to start again. Time to rebuild.
From now on, only black coffee — no milk, no sugar.

Time to get back into the power of ketosis.
