You don't need to read these posts in order. You also don't need to read all of them.

This isn't a book: it is a documentation of a system written as standalone observations about ultramarathon training. Think of it as a collection of field notes rather than a narrative arc. There are specific paths through the content depending on what you want to understand.

BTS Ultra 100K - 2025

If You Want to Finish Your First 100K

If you want to understand the minimum viable system to finish a 100 kilometer ultramarathon, here is your reading path:

Foundation:

• The Algorithm of Endurance: Why I run.
• The Architecture of Endurance: What you're learning (the system I built).
• Bio-Structural Audit: Understand your body before training.
• Red Flags & Screening: Prevent injury before it happens.

Then Skip Straight to Ultra:

• The Mindset Shift: Why 100K is different from marathoning.
• Strategic Periodization: How to structure 6 months of training.
• Ultra-Specific Work: Building durability and vertical climbing.
• The Ultra Stomach: How to fuel for 20 plus hours.
• Psychology & Grit: Mental frameworks for the hard moments.
• Crew Management: How your support team makes or breaks your race.
• Problem-Solving: What to do when things go wrong.

Then (Optionally) Understand Why:

• Bioenergetics: How your body actually produces energy.
• Fuel Selection: Understanding metabolism and fat adaptation.
• Threshold Diagnostics: Measuring your actual fitness.
• Data Integration: Knowing what your watch is actually telling you.

This path takes you from identity → understanding your body → building ultra-specific fitness → executing a race → understanding why it works.

Total time: 6-7 hours of reading + 24 weeks of training.

In late 2024, I made a decision that seemed insane at the time: I was not going to hire a running coach.

Not because I couldn't afford one. Not because I didn't believe in coaching. In fact, I have seen the value of professional guidance firsthand. I was coached as part of the ASICS Marathon Team in 2023 and influenced by the Pocari Sweat Sports Science team while serving as a Pocari Sweat Marathon Pacer in 2024.

However, I realized something about myself: I think better when I understand the system, not just the directives.

A coach would tell me: "Run 10 kilometers easy on Tuesday. Do four repeats of 1600 meters hard on Wednesday."

I would follow the plan. If it worked, great. If it did not, I would blame the plan or myself, but I wouldn't actually understand what happened.

Instead, I decided to reverse-engineer my own training system from first principles, synthesizing methodologies from foundational texts like Daniels’ Running Formula, 80/20 Running, and Advanced Marathoning.

Why You Don't Need a Coach (But You Need a System)

I'm not anti-coach. Good coaches are valuable. But most runners don't need a coach. They need a system. Here's the difference:

A coach is a person who:

• Knows your history, injuries, and psychology.
• Adjusts your plan in real-time based on how you're responding.
• Provides accountability and motivation.
• Costs $30 to $300 (Rp5.000.000) per month.

A system is a framework that:

• Is replicable and teachable.
• Removes guesswork from training decisions.
• Can be personalized without external help.
• Costs $0 (or the price of understanding it).

As a busy professional, I don't have the bandwidth for a coach. But I have the intellectual capital to understand training systems. I have the time to document what works. And I have the obsession to test it rigorously.

This is what a system gives you: the ability to adapt to your reality.

Because life isn't static. Work stress spikes. You get injured. You travel. Your schedule changes. A fixed training plan breaks under this complexity. But a system you understand can flex.

When my work spiked in August 2025, I didn't abandon training. I reduced intensity while maintaining volume. I ran 80% easy runs instead of 60%. My fitness didn't decline. It actually improved because I managed stress better.

A coach's plan would have said: "Follow this or don't." My system said: "Adapt while maintaining the principles."

There is a moment that happens around kilometer 80 of an ultra trail race. Your legs feel like concrete. Your mind is screaming. The pain isn't sharp anymore; it is dull and omnipresent, as if your body is slowly surrendering to physics.

I hit that moment three times in 2025.

Three ultra trails in eight weeks. Three 100-kilometer races. Three times I convinced myself that my legs would keep moving when my brain insisted they were finished. Three times I discovered something I did not know about myself.

But here is what surprised me most: it was not the ultramarathon that changed me. It was the realization that everything I had learned as a business technologist, including every framework, system, and principle I built while running my company, applied directly to running 100 kilometers through mountains.

This is my origin story in running.

The Desk-to-Trail Transition

My name is Anggriawan Sugianto. I am the Chief of Suitmedia, a digital consulting firm in Jakarta with over 200 employees. I spend most days in optimizing workflows, analyzing spreadsheets, and making decisions that affect growth.

I also run 100-kilometer races through mountains.

These two facts may seem disconnected, but they are not. They represent the same skill applied to different domains.

In 2023, I started running seriously. I do not mean the casual 10-kilometer runs often seen on social media. I mean distance: the kind that takes hours, demands total consistency, and reveals your true character.

At first, it was for health. Then it became a test. Finally, it became an obsession with understanding how systems work.

Most people who run endurance distances follow one of two paths:

1. Outsourced: Hire a coach, pay the fee, and follow the plan.
2. Amateur: Download a generic plan from the internet and hope for the best.

Both approaches assume you need an external structure or that you cannot think for yourself. I rejected both.

As a strategist, I have spent a decade learning to think in systems. I build products using frameworks. I make hiring decisions using matrices. I structure companies around principles rather than hunches.

It seemed illogical to abandon that mindset the moment I wanted to run 100 kilometers.

In late 2024, I decided to become my own coach.

This was not due to arrogance, but because I had a unique advantage: the ability to reverse-engineer the system. I had the time to test hypotheses and document what actually works.

By 2025, I had proven the system works.

Di tengah keriuhan transportasi publik kita, entah itu di gerbong KRL yang padat atau di sela antrean ojek daring, ada sebuah pemandangan baru yang seragam: layar gawai yang digenggam vertikal dengan volume suara yang tipis namun dramatis. Masyarakat kita sedang dijangkiti demam mikro-drama atau "dracin pendek". Hanya dalam durasi satu hingga tiga menit per episode, drama ini mampu menyihir jutaan orang, mulai dari pekerja sektor informal hingga eksekutif yang mencari pelarian sejenak dari keletihan mental (decision fatigue).

Sebagai praktisi Customer Experience (CX), saya melihat keberhasilan mikro-drama bukan terletak pada kemegahan sinematografinya, melainkan pada ketangkasannya membedah anatomi psikologi dan perilaku manusia modern di era seluler.

Ilustrasi: Menonton Mikro-Drama di dalam MRT

Matinya “Format Menengah”

Secara historis, kita terbiasa dengan durasi standar 22 menit untuk sitkom atau satu jam untuk drama televisi. Namun, hari ini kita menyaksikan apa yang saya sebut sebagai The Death of the Middle-Form. Konsumsi konten kini bergerak ke dua titik ekstrem: format sangat panjang seperti podcast berjam-jam, atau format ultra-pendek.

Mikro-drama mengeksploitasi interstitial time, celah waktu sempit di sela fragmentasi kesibukan kita. Ia menawarkan frictionless consumption. Tanpa perlu komitmen waktu besar, ia hadir mengubah waktu tunggu yang "mati" menjadi jendela hiburan yang intens. Di sinilah letak kemenangannya: ia tidak meminta waktu kita, ia mencurinya di sela-sela kesibukan.

Pembajakan Vertikal dan Efek Zeigarnik

Platform mikro-drama melakukan vertical hijack. Dengan format vertikal yang memanjakan ergonomi satu tangan manusia, teknologi ini menyesuaikan diri dengan ritme fisik kita, bukan sebaliknya. Ini bukan sekadar soal rasio aspek layar, melainkan desain yang sadar konteks (context-aware design).

Daya pikatnya kian adiktif berkat penerapan gamified cliffhangers. Setiap episode dirancang menggunakan Zeigarnik Effect, tendensi psikologis di mana otak manusia cenderung merasa terganggu dan terus teringat pada hal yang belum selesai. Rasa penasaran ini dikomodifikasi sedemikian rupa, sehingga pengguna secara bawah sadar akan sulit melepaskan layar sebelum cerita tuntas, meski harus membayar per episode.

Secara kultural, mikro-drama di Indonesia sukses karena menyentuh "DNA" lokal. Tema seperti balas dendam menantu yang terzalimi atau CEO yang menyamar adalah topik universal yang menawarkan gratifikasi instan melalui narasi “justice porn”, kepuasan melihat keangkuhan ditundukkan oleh kebenaran. Strategi ini lalu diperkuat dengan algorithmic funneling yang presisi di Facebook, Instagram, atau TikTok, menjerat audiens masuk ke dalam corong konversi (funnel) menuju aplikasi utama.

There is a specific kind of silence that only exists at 3:00 AM on a muddy trail in the middle of a race. Your headlamp is failing, your quads feel like they've been tenderized by a mallet, and your brain is screaming—rationally, logically—that you should stop.

Over the years, I've realized that the "algorithms" I learned in ITB and the "frameworks" I mastered in KAIST MBA are exactly what keep me moving on the trail. And conversely, the "grit" of the trail is what allows me to lead Suitmedia through the volatility of the Indonesian tech landscape.

Success is isomorphic. The same principles that scale a company win a mountain race. These are the mental models I live by, grouped into the pillars that define my world.

I. How I Think

These are the foundational models for clarity. If my internal "Map" is wrong, no amount of speed will get me to the right destination.

1. The Logic of Truth

Before you can solve a problem, you have to see it clearly.

• First Principles Thinking: Strip a problem to the core truths. Don't reason by analogy; build your own logic from the ground up.
• Occam's Razor: When faced with two competing theories, the simplest one is usually the truth. Avoid over-engineering your life.
• Map vs. Territory: Your mental models, plans, and spreadsheets are just "maps." Never confuse the abstraction with the messy reality of the "territory."
• Circle of Competence: Be brutally honest about what you know and where your expertise ends. Play only in games where you have an edge.

2. Strategic Decision Making

Choosing the path when the fog of war (or mountain mist) is thick.

• Inversion: Instead of asking how to succeed, ask "How could I spectacularly fail?" Then, build systems to avoid those specific pitfalls.
• Probabilistic Thinking: Life is a game of odds, not certainties. Focus on making high-probability bets rather than chasing sure things.
• Regret Minimization: When at a crossroads, choose the path that your 80-year-old self would be most proud of.
• Sunk Cost Fallacy: Having the courage to walk away from a bad project or relationship, regardless of how much time or money you've already invested.

3. The Physics of Growth

How to ensure effort results in exponential progress.

• The Pareto Principle: Identify the 20% of inputs—habits, clients, or training—that produce 80% of your results. Ruthlessly cut the rest.
• Compounding: The most powerful force in the universe. Tiny, 1% gains repeated over a decade create exponential wealth, wisdom, and fitness.
• Velocity vs. Speed: Speed is how fast you move; Velocity is speed plus direction. It's better to crawl toward the right goal than sprint toward the wrong one.
• Theory of Constraints: Every system has one primary bottleneck. Improving anything else is an exercise in futility. Find the bottleneck; widen it.

4. Human & Social Dynamics

Navigating the "Human API" in leadership and life.

• Incentives: Show me the incentive, and I will show you the outcome. If you want to change behavior, change the reward structure.
• Hanlon's Razor: Never attribute to malice what can be adequately explained by neglect or a simple mistake. It saves a lot of unnecessary anger.
• Social Proof: We are biologically wired to mimic others. Use this awareness to choose mentors wisely and avoid groupthink traps.
• Pygmalion Effect: People generally live up to or down to the expectations we set for them. Lead with high belief in your team.

5. Systemic Resilience

Building a person in me that gets stronger under pressure.

• Antifragility: Designing your life so that you don't just survive the storm—you actually get stronger because of them.
• Feedback Loops: The shorter the gap between an action and its feedback, the faster you can iterate and improve.
• Margin of Safety: Always leave a buffer—in your schedule, your bank account, and your heart rate—for the unknown unknowns.
• The Power of Narrative: The stories we tell ourselves about our failures determine whether they become traumas or fuel for growth.

This post is about a 5-year journey that changed everything—and what it taught me about resilience, strategy, and becoming who you thought you couldn't.

The Impossible Beginning

In 2020, I was that guy: an ITB alumnus running a creative digital agency, completely sedentary, leaning hard into unhealthy habits. I wasn't sick, wasn't in crisis (yet), but I was fractured. The pandemic hit, and something in me broke open—not dramatically, but quietly. I hit Obese level 1. My cognitive function tanked. I remember calling it "slow thinking"—like my brain was running at half speed. I'd sit in strategic meetings and feel... foggy. Unreliable. Not myself.

In August 2020, something shifted. I decided to run 5 kilometers.

I remember telling people: "I'm going to run a marathon one day." They laughed. Not unkindly, but the kind of laugh that says sure, buddy. And honestly? I didn't believe it either. A marathon felt like claiming I'd climb Everest. A 100K? Laughable. Impossible.

But here's what I didn't understand then: impossibility is just a lack of systems.

By July 2023, I was running marathons with the ASICS Marathon Team. By 2024, I was a Pocari Sweat Marathon Pacer. And in 2025—just 5 years after that first terrifying 5K—I ran not one, but three 100K ultra-trail races in eight weeks.

When I delivered this presentation on October 30, 2025, I had already completed two of them: BDG Ultra and Trans Jeju by UTMB. I was mid-mission, riding the momentum toward the third race (BTS Ultra), still processing what was happening.

Now, writing this in January 2026, with all three finishes behind me, I can see the full arc of what happened.

100+ km. Done.

The journey wasn't about getting faster or stronger (though both happened). It was about discovering that the person I thought I was—sedentary, undisciplined, limited—was a fiction. And once you see through that fiction, you can't unsee it.

Along the way, I learned seven fundamental truths. Not secrets, exactly. More like operating principles—frameworks that work because they're rooted in how humans actually function, not how we wish we functioned.

These aren't just running principles. I've watched them reshape how I lead Suitmedia, how I make decisions under uncertainty, how I handle the scaling challenges of a growing business. They're transferable. And I think they might work for whatever your "100K" is.

Secret #1: The Power of Showing Up (Consistency Beats Intensity Every Time)

The Real Problem with Motivation

Let me tell you about motivation: it's a liar.

Everyone approaches running (or fitness, or any ambitious goal) the same way: they wait for motivation. They imagine themselves as the kind of person who loves running. They picture early mornings, sunrises, that runner's high. They motivate themselves into a frenzy and commit to running 5 days a week, 10km per session.

Then Tuesday comes, and they're tired. Wednesday, it rains. Thursday, work runs late. By Saturday, they've missed three sessions, feel like failures, and quit.

This is the motivation trap. And I fell into it hard in those first months.

What changed everything was understanding BJ Fogg's Behavior Model: Behavior = Motivation + Ability + Prompt. You can't rely on motivation because motivation is volatile. It spikes and crashes. But you can control ability and prompts.

Here's what I did differently:

I started absurdly small.

My first running routine wasn't 10km, 5 days a week. It was 15 minutes of walk-jog, 3 times a week. That's it. Not impressive. Not Instagram-worthy. But doable. Even on bad days, even when I was tired or stressed, 15 minutes felt achievable.

The magic wasn't in the 15 minutes themselves. It was in building the habit first, the pace later.

I treated running like a professional appointment—non-negotiable, scheduled, the same time each week. Not because I loved it, but because it was on the calendar, and I show up to calendar items. This sounds obvious, but most people don't do this. They think discipline comes from feeling like it. Discipline actually comes from removing the decision.

By month three, running 15 minutes 3x a week felt as normal as brushing my teeth. My brain stopped negotiating it. Then I extended to 20 minutes. Then to 5 days a week. Then the distances grew. But the foundation was the habit—showing up, even when it sucked.

The "Good Enough" Run

Here's something they don't tell you: not every run needs to be great.

In October 2025, I had completed a 266-week running streak—5+ years without missing a single week. Some of those runs were transcendent. Most were forgettable. Some were genuinely ugly. I remember a 6am run in Jakarta heat where I barely made it 5km and felt like I'd been hit by a bicycle. But I showed up. That run counted the same as the perfect long run on a cool morning.

The breakthrough moment came when I stopped chasing the perfect run and started celebrating the completion of effort. Some weeks, "showing up" meant a slow 8km jog in humidity. Some weeks it meant a brutal 30km weekend run. Both counted. Both built the streak.

This is counterintuitive but critical: Discipline is built by showing up on the bad days, not the good ones. The good days take care of themselves.
