The Starting Line
2025⟶2026
09:08 ⟶ 08:18
Quiet progress.
Fifty minutes faster.
But something didn’t feel right.
Last year, I finished and walked away clean.
No real damage. No cramps. No collapse.
This year, I was stronger.
And I broke.
The Path
The beginning always lies.
You feel smooth.
Light.
Controlled.
You think:
“This is the day.”
Every time.
I had the same thought again.
I’ve trained.
I know what I’m doing.
This time the wall won’t come.
But it always comes.
Not in the mind.
In the body.
Around 35 km, things changed.
Not dramatic.
Just small signals:
Cadence dropped.
Muscles tightened.
Eating felt harder.
Then it compounds.
Climbs slow.
Legs stop responding.
Running becomes negotiation.
By the final climb, I had to stop.
Not because I wanted to.
Because my body shut it down.
Cramps.
Full stop.
The Illusion
I never thought about quitting.
Not once.
That used to be the test.
Can you keep going?
Now I see it differently.
The problem is not:
“Will I stop?”
The problem is:
“Can my body continue producing?”
My heart was fine.
My mind was clear.
But the system failed.
The Other Race
There was another layer.
People.
One runner blocked the trail.
Slow. Unaware.
Didn’t let others pass.
Later, he surged past me.
Then slowed again.
At first, I thought:
“This guy is an asshole.”
Later, I saw it differently.
He wasn’t malicious.
He just wasn’t aware.
Fatigue narrows people.
Everyone is inside their own race.
At the finish line, I slowed down.
People were taking photos.
Holding the tape.
I waited.
Then someone sprinted past and broke through it.
Different rules.
Different priorities.
Same race.
The Shift
Last year:
I chose to slow down.
This year:
My body made the decision.
That is the difference.
This is not about toughness.
I had enough of that.
This is about durability.
Fueling.
Muscle endurance.
Mechanical efficiency.
The real limit is not pain.
It is system failure.
The Finish Line
I did not discover my limit.
I discovered where my system breaks.
That is more useful.
Because that can be trained.
