Anggriawan Sugianto

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.

BDG Ultra 2025 - My first 100K

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.

The Turning Point: Three 100K Races in Eight Weeks

In 2025, I executed a plan that was both aggressive and calculated: I ran three 100-kilometer ultramarathons in eight weeks.

1. September 13: BDG Ultra 100K (30h 17m)
2. October 18: Trans Jeju by UTMB 100K (23h 37m)
3. November 8: BTS Ultra 100K (27h 24m)

Most coaches would warn that such a schedule leads to injury, overtraining, or burnout. That is a reasonable assumption. However, something unexpected happened: I got stronger.

The first race taught me how to survive physically and mentally. The second race taught me efficiency without trekking poles. The third race taught me how to endure when my legs were fatigued. Each race was a data point that refined my system.

This was not reckless; it was controlled risk. I had a hypothesis: "Can I run three 100Ks in eight weeks without injury and actually improve my fitness?"

The answer was yes, but only because I was not flying blind. I relied on:

1. A Periodization Framework: Base → Build → Peak.
2. A Fueling Protocol: Tested and verified on every long run.
3. A Recovery System: Prioritizing sleep, nutrition, and active recovery.
4. Data Collection: Tracking every run and physiological metric.
5. Flexibility: Adjusting the plan when the data signaled a problem.

This is what separates intelligent risk-taking from recklessness. It is the same difference that exists between strategic investing and gambling.

By November 2025, I'd proven something to myself: the system works.

Running 100 kilometers isn't magical. It's mechanical. It's systematic. And it's replicable.

Not everyone needs to run three 100Ks in eight weeks. That was my experiment. But everyone who wants to run 100 kilometers needs a system. And that's what I learned.

The 2026 Mission: BTS Ultra 170K

The BTS Ultra 170K is not just a marathon. It is an Indonesian ultra trail race spanning 170 kilometers of technical mountain terrain over multiple days.

A hundred miles.

That is nearly twice the distance of my 2025 races, roughly equivalent to running from Jakarta to Bandung non-stop. This involves a day and a half of continuous effort, punctuated only by brief naps.

This is my 2026 goal.

I am not chasing this goal for the sake of distance or social media validation. I am doing it because the it represents the ultimate pressure test for everything I have learned about training systems, nutrition, and mental resilience.

Here's what BTS Ultra 170K demands:

1. Pure Endurance: Sustaining effort for 39 to 42 hours.
2. Technical Skill: Navigating unforgiving Indonesian mountain terrain.
3. Nutrition Mastery: Managing every calorie and electrolyte under extreme stress.
4. Mental Resilience: Managing the brain mutiny that occurs after 120 kilometers.
5. Recovery Architecture: Optimizing the days between training to ensure progress.

Every system I have built is being tested in this single event. But the takeaway is this: you do not need to run the BTS Ultra 170K to use this system. Whether you want to finish your first 100K or simply understand the principles of endurance, the framework remains the same.

Success is a matter of engineering.
