The silence at 10 PM in Selo, Boyolali is not like other silences. It's not the quiet of sleep. It's thick, wet, and heavy—the kind of quiet that happens when a sleeping volcano is watching you from inside the clouds. I stood at the start line of Merapi 360°, looked at my watch, then looked down the dark road ahead. Seventy-seven kilometers of asphalt stretched into nothing. No trails. No rocks to…
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…
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…
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. Trans Jeju 100K Finisher Totem 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…
The mountains don’t care about your profit and loss statement. I learned this the hard way in 2025. This year was a study in extreme contrast—a chaotic, beautiful, and sometimes heartbreaking symphony of high performance and hard landing. Physically, I reached a peak I once thought was reserved for the elite. Community-wise, I tried to pour into others even when my own cup felt dangerously low.…
It was supposed to be the grand finale. The last battle in my 2025 ultra trail saga—a year packed with challenge and grit. Three 100K ultras in eight weeks. One race each month. I was tired, yes, but more than that, I was determined. This was the moment to seal the deal. Siksorogo Lawu Ultra 80K. The last dance of the year. Campground Sekipan, Tawangmangu I’m no stranger to this race. Not at all.…
Okay, let's be honest. After running two 100-kilometer ultra-trail races in just five weeks, my body should have been officially on strike. Most people would be horizontal, maybe with a nice warm compress and a long, philosophical stare at their ceiling. BTS Ultra: The most beautiful ultra-race I ever run Yet, here I was, standing at the BTS Ultra start line. This was the third, and final, monster…
Sebagai seorang pegiat ultra-endurance sport , yang telah menyelesaikan 9x marathon sejak 2023 dan baru saja menyelesaikan 100K ultra trail di BDG Ultra dan Trans Jeju by UTMB , saya menyadari betul krusialnya peran teknologi pendukung. Selama empat tahun terakhir, smartwatch lama saya telah menjadi instrumen esensial. Namun, di tengah tuntutan ultra trail race yang makin intens, saya mulai…
There's a funny thing about pushing your limits: the moment you cross a finish line, part of you vows "never again." But then, a stubborn whisper begins, a quiet pull towards the next impossible dream. TransJeju by UTMB 2025 After BDG Ultra 100K , my body definitely screamed for a proper break. Five weeks went by, letting my muscles heal and my mind catch up to the wild idea of doing it all again.…
A Wild Leap of Faith – For a while now, running has been my happy place. It’s where my thoughts get sorted, my legs get a good workout, and sometimes, I find a deep truth hiding in the dust of a trail. I’ve run full marathons. I even managed to finish some ultra trail races. Last year, my BDG Ultra 64K felt like my own personal Mount Everest. It was my longest run ever, with the most climbing. I…
Hello there, fellow traveler on this wild journey called life! Or, in my case, on this wild journey called… a very, very busy running calendar. You know those moments when life throws you a delightful curveball, and suddenly your perfectly laid plans take an unexpected, exhilarating detour? Well, grab a cup of kopi, because that's pretty much the story of how I found myself toeing the starting…

Pada hari Selasa, 19 Agustus 2025, kami menorehkan jejak harapan di SDN Rawa Badak Utara 11, di mana puluhan relawan dari berbagai profesi meluangkan satu…
My rational brain often questions my decisions at 2 AM. Especially when I'm voluntarily running up a mountain in 11°C weather, having just put my legs through the wringer a mere seven days prior. But then, there's the call of the trails, a whisper that promises profound conversations with myself, a kind of madness that makes perfect sense to a runner's soul. And that, my friends, is the story of…
A Masterclass in Beautiful Chaos There's a certain kind of madness that pulls us back to the starting line, isn't there? For me, it's an enduring, slightly masochistic love affair with running, a relentless pursuit of new challenges, and perhaps, a quiet curiosity about how much more my body and mind can endure before they send a strongly worded letter of resignation. This year, the BTN Jakarta…
You know, there’s something about mountains. They just stand there, silently calling our names, promising adventure, breathtaking views, and… well, a whole lot of sweat and pain. As a runner, especially one who keeps finding himself tackling ultra trails, I’ve often asked myself, "Why do I do these things? Ngapain siiih… mending tidur!! 😴" Honestly, who needs to stumble through a forest at 2 AM,…
Di tengah gemuruh Jakarta, saat mentari mulai mengintip dari balik gedung-gedung pencakar langit, ada momen magis setiap pagi ketika aroma kopi pagi dari warung-warung kecil berpadu dengan lantunan adzan subuh dari masjid yang melintasi udara. Ini adalah gambaran nyata keberagaman agama yang harmoni: sebuah simfoni kehidupan yang menjadi bagian dari sehari-hari di negeri ini. Seolah tanpa kita…
Coast to Coast Ultra Night Trail. The name alone sends chills down my spine. I analyzed the data and pored over past races to understand this beast. It wasn't perfect. It was a wild, chaotic symphony of iron will, searing pain, and choices that flirt with deep regret, all set against the backdrop of Yogyakarta’s hidden beauty where every mile becomes a story told for years to come—a haunting song…
Ever feel like your life is a never-ending to-do list? Buckle up, because 2024 was a wild ride for me, a chaotic blend of ultra-marathons and business challenges. From pacing marathon runners in Bandung to conquering mountains in Bali, I'm still trying to figure out how I survived (and maybe even thrived!). Here's the story of my year, month by insane month: January: New Beginnings and Feeling…
Siksorogo. Namanya saja sudah bikin bulu kuduk merinding! Gunung Lawu bukan trek biasa, lho. Tempat ini punya reputasi tersendiri—mistis dan menantang, siap menguji mental kita. Saya mendaftar untuk kategori 50K, jalur yang membawa kami melewati keindahan alam dari Sekipan hingga Kebun Teh Kemuning. Satu hari sebelum race, saya mengambil race pack di Sekipan sore-sore. Saat itu, gerimis sudah…
BDG100. Mendengar namanya saja lutut sudah terasa mau copot. Race ini terkenal dengan elevasi yang menantang, tanjakan yang membuat meringis, dan pemandangan yang menyegarkan jiwa. Tahun ini saya memutuskan untuk ikut gila. Mengapa? Karena di balik setiap tantangan fisik yang berat selalu tersembunyi pelajaran mental yang berharga. 🙈 Buat saya, BDG Ultra ini adalah pendakian yang panjang dan…
Bali adalah pulau impian dengan sejuta pesona. Namun tahun ini, Maybank Bali Marathon bagi saya bukan sekadar lari di tengah pemandangan sawah dan deretan pura yang megah. Ini adalah sebuah kisah tentang paradoks. Ini tentang rencana yang berantakan tetapi menghasilkan akhir yang membahagiakan. Singkatnya, ini adalah cerita mengenai bagaimana saya berhasil meraih personal best meskipun hanya…
Maraton bukanlah sekadar lomba lari, melainkan semacam ziarah jiwa. Ribuan kaki melangkah bersama, bukan hanya untuk mengejar catatan waktu, tetapi juga untuk menemukan kekuatan dalam diri, untuk menguji batas kemampuan, dan untuk saling menyemangati di sepanjang jalan. Di Pocari Sweat Run 2024, saya datang sebagai seorang pacer, seorang pemandu yang bertugas menjaga ritme. Namun, di tengah lautan…
Pada 11 Mei 2024, saya mencoba sesuatu yang baru dalam perjalanan lari saya dengan ikut serta di BTR Ultra di Kintamani, Bali. Ini adalah pengalaman pertama saya dalam ultra trail run, dengan jarak 55 km yang benar-benar menguji fisik dan mental saya. Jalurnya berada di sekitar Danau Batur, melewati Gunung Batur dan Gunung Abang, jadi selain tantangannya, saya juga disuguhi pemandangan yang luar…
Since early 2023, I've been conducting CTO-Intern catchup sessions where I meet with new interns in batches over coffee to get to know them individually. During these sessions, I typically inquire about their backgrounds, motivations, and hobbies. Towards the end of the catchup, I allow them to ask me anything, with each person having the opportunity to pose one question. Thus far, I've noticed…
In 2023, I found myself becoming more involved in running, as reflected in my blog posts this year. This post serves as my annual reflection on the events of 2023. I hope we can extract some lessons from these experiences. 2023 : Year of Running January As the new year started, we got busy planning and setting goals for 2023. Alongside our work, I made time for running. On January 1st, I ran 23…
