The Half Marathon That Humbled Me: A Lesson From Glampies Intentionality Run

28th June 2026. 21.1 kilometers. 2 hours and 1 minute. And one of the biggest reality checks of my two-year running journey.

Going into the Glampies Intentionality Run, I felt overly comfortable.

Five months earlier, I’d crossed the finish line of my first Full Marathon at TMM. Two weeks before this half marathon, I’d smashed my 10K personal best — 48:09. And my Half Marathon PB, set six months back, stood at a solid 1:47 hours. In my head, the math was simple: if I could run 42.2 kilometers, and if I could run a fast 10K, then 21.1 kilometers should be a walk in the park.

I hadn’t trained properly in months. My long runs were sporadic at best, non-existent at worst. But I didn’t let that bother me — I had the FM finisher’s medal to back up my confidence, and confidence, I told myself, would carry me through.

It didn’t.

The First 15K: Everything Going to Plan

The gun went off, and I settled into a rhythm that felt almost effortless. Average pace of 5:15/km, mile after mile clicking by exactly as I’d imagined. I felt strong. I felt fast.

By the 15K mark, I was still on pace, still feeling good, still convinced I was going to clock another PB. That’s just how most of my runs had gone — some split along the way, whether it was the 1K, the mile, or the 5K, almost always ended in a new personal best. And then, without warning, my body disagreed.

When the Wheels Came Off

Somewhere after 15K, cramps hit my hamstrings and glutes — the kind of cramps I had never experienced in two years of running. Not a warning sign I could run through. My hamstrings and glutes just locked up, again and again, right when I needed them most.

The last 6.1 kilometers became less of a run and more of a negotiation with my own legs. I was limping. Stopping. Stretching. Willing myself forward a few hundred meters at a time. Every runner who has hit a wall knows this feeling — when your mind is still racing but your body has simply stopped listening.

There was no PB conversation left at that point. The only goal was the finish line, however I could get there.

I crossed it in 2:01 hours — a full 14 minutes slower than my HM PB of 1:47. Not the time I’d walked in expecting. But given how the second half of that race unfolded, it might be one of the most earned finishing times of my running life.

The Lesson I Didn’t Know I Needed

Here’s what this run taught me, and it’s a lesson I don’t think I could have learned any other way: finishing a Full Marathon does not make a Half Marathon easy. Chasing a 10K PB doesn’t make any distance “easy,” period. Every distance demands its own respect, its own training, its own preparation — regardless of what you’ve already accomplished.

I had let one big achievement convince me that fitness is a permanent state rather than something you build and maintain, day after day, run after run. It isn’t. Consistency and discipline aren’t just nice ideas you put on a running t-shirt — they’re the only real tools that separate a good race from a day spent limping through the last 6 kilometers.

Some runs hand you a personal best. Some runs give you that pure, uncomplicated runner’s high. And some runs — like this one — give you something less glamorous but far more valuable: a hard, honest lesson that sticks with you long after the soreness fades.

Looking Ahead

I have two months until my next Full Marathon — NMDC Hyderabad. Glampies Intentionality Run was, in every sense of its name, a moment of forced intentionality. It stripped away the overconfidence and handed me back a clear, uncomfortable truth: I have work to do, and no past finish line is going to do that work for me.

So this is me, starting over with humility instead of assumption — back to the long runs, back to consistency, back to earning it one kilometer at a time.

Because the next 42.2 kilometers won’t care what I’ve already run either.
