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 International Marathon (JAKIM) 2025 became my next great dance partner – a chance to tackle the vibrant, pulsating heart of my own city.
I stood there at the starting line, perhaps a little too confident in my pre-race crowd analysis, thinking I had this whole "city marathon" thing figured out. Oh, the sweet innocence of a runner before the gun goes off. It's a familiar story, really; we plan, we prepare, and then life (or 42.195 kilometers of it) decides to throw a party of its own, usually without consulting our meticulously crafted itineraries.

Sweat, Strategy, and Smart Recovery
Barely a sigh of relief after the epic Semarang Mountain Race – a beastly 50K ultra trail with a lung-busting 3500m elevation gain back on April 13th – I knew I needed to pivot. Fast. My body, still humming with the echoes of mountain paths, needed a smart transition. So, like any self-respecting tech enthusiast with a penchant for pain, I turned to AI. Yes, my personal 11-week marathon training plan, starting April 14th, was meticulously crafted by an artificial coach, all aimed at a lofty 3:52:00 finish for JAKIM, a crisp 5:30/km average pace.
My weeks quickly found a rhythm, a strategic dance of pavement and gym floor: Tuesday brought 10-12K at an easy pace, a chance for the legs to remember how to move without fighting gravity. Wednesday was the sharp, breathless sting of interval runs, building speed and grit. Thursday, the delightful soreness of strength training, reminding me that a runner needs more than just legs. Friday, a focused tempo run to practice holding that race-day pace, and then, the grand finale, Sunday's long run, always at least 21K, sometimes pushing much further.
The entire 11-week block was a meticulously planned crescendo: Week 1, a much-needed recovery to mourn the mountains. Then, weeks of building base and increasing intensity, followed by a peak mileage phase (hello, 30-32K long run on Week 8!) with a clever supercompensation dip on Week 5 to keep the body guessing and growing. Every stride, every pace, calculated by the venerable Jack Daniel's VDOT method – because apparently, even running has its own sophisticated cocktail of numbers. My weekly mileage consistently topped 50K, a testament to the idea that sometimes, you just have to show up and put in the work, even when your inner voice is bargaining for a nap.
