What 205 Kilometers Taught Me About Pacing

The Ride I Was Not Ready For

I had owned the bike for fourteen days. I had ridden it maybe four times, mostly short loops to get used to the gears and the position on the bars. Then a friend mentioned a route, a long one, point to point through a string of small towns, and asked if I wanted to join.

I said yes before I had thought it through properly. That is usually how I end up in these situations. Not because I am reckless, but because I would rather find out what I can actually do than guess from the safety of not trying.

Why I Said Yes Anyway

I had no real sense of what 205 kilometers meant in the body. I just knew it was further than I had ever gone, by a wide margin, and that the gap between what I had done and what I was about to attempt was big enough to be interesting instead of just intimidating.

So I packed two bottles and some bars, and showed up at the start without a real plan beyond "keep pedaling." The first hundred kilometers went fine. Better than fine, honestly. I was riding faster than I expected, feeling strong, and quietly convinced this was going to be easier than everyone made it sound.

That confidence did not last.

What Happens at Kilometer 140

Kilometer 140 is where the legs stop negotiating and start making demands. There is no gradual warning system. One moment you are riding normally, the next your body sends a very clear message that it has reached the end of what it agreed to at the start of the day.

This is the point where most people either panic or quit. Panic looks like sprinting to get it over with faster, which only spends what little is left even quicker. Quitting looks exactly like it sounds, and on a remote stretch of road, it is not really an option anyway.

I did neither, mostly because the route did not leave room for quitting, and panic only occurred to me afterward, once I had time to think about how close it had felt.

The Three Things That Actually Helped

What got me through the last sixty kilometers was not willpower in the dramatic, movie-montage sense. It was a handful of small, unglamorous decisions, repeated over and over.

• Dropping into a smaller gear before my legs forced me to, instead of waiting until I had no choice in the matter.

• Eating on a timer instead of waiting until I felt hungry, because by the time hunger shows up on a ride like that, it is already too late to fix it.

• Picking the next sign, tree, or turn as the only goal, instead of letting my head do math about the distance still ahead.

None of these are exciting strategies. That is more or less the point. The exciting ones, the ones that sound good in a recap, are usually the ones that fail you exactly when you need them most.

Pacing Off the Bike

I think about that ride more often than makes sense for a single afternoon on a bike I barely knew how to handle. The lesson generalizes further than cycling, which is probably why it stuck.

Most of the times I have burned out on a project, it was not because the project itself was too big. It was because I treated the first third of it the way I treated the first hundred kilometers of that ride: like there was no limit to draw from, like the strong feeling at the start would simply continue if I just kept going at the same pace.

It never does. There is always a kilometer 140 hiding somewhere in a long piece of work, a point where the early energy runs out and what is left has to come from somewhere more deliberate.

Where I Apply This Now

These days, when I start something that is going to take weeks instead of hours, I try to ask the kilometer 140 question early instead of late: what does the boring, sustainable version of this look like, and can I start there instead of waiting until I am forced into it.

In practice that means working at a pace that feels almost too slow in the first few days. That discomfort is different from physical exhaustion, but it is real, and it is the version of starting that actually finishes. It is also the version that does not need a dramatic recovery afterward, because nothing got spent that should have been saved.

It shows up in training too, especially now that an Ironman is somewhere on the horizon rather than a vague idea. Long-course endurance sport runs entirely on this same principle, scaled up. You do not get to feel strong all day on confidence from the first hour. You get to feel strong because you left something in reserve for the part of the day that asks for it.

The Takeaway

Pacing is not about going slow for its own sake. It is about not spending everything you have in the first hour, because the version of you at kilometer 140, or week six of a project, or day three of a launch, is going to need some of what you saved.

I have not done another 205 kilometer ride since, mostly because two weeks of bike ownership turned out to be a strange amount of preparation and I would genuinely like to prepare properly next time. But the pacing lesson stuck, and it shows up in places that have nothing to do with a bike at all.

What I Would Do Differently Next Time

If I am honest, the ride worked out, but it worked out because I got lucky on a few things that I would not want to rely on again. The weather stayed mild. Nothing mechanical went wrong. My body happened to respond well to a stress it had never seen before. None of that was planning, and planning is the part I actually want to get right next time.

A Short List of Adjustments

A few concrete things would change if I lined up the same distance again, on purpose this time instead of by accident.

• Fuel earlier and more consistently, on a schedule rather than reacting once the gap is already showing.

• Build up the long rides gradually beforehand, instead of jumping straight from short loops to the full distance in one attempt.

• Carry a real plan for the last quarter of the ride, written down beforehand, instead of figuring it out in the moment while already depleted.

None of these adjustments are about going faster. They are about removing the parts of the experience that were left to chance the first time, so the next long ride is a test of pacing rather than a test of luck.

That distinction matters more to me now than it did two weeks into owning a road bike, mostly because I would like the next hard thing I take on, on or off the bike, to be hard for the right reasons.
