Tokyo Marathon Training: The Journey Begins

Here’s the simple version: I’m officially training for the Tokyo Marathon. On March 1, 2026, I’ll be standing on that start line with one clear goal: run under three hours.

That number has been in my head for more than a decade. My best marathon is 3:09, but that was 12 years ago. Back then I thought, “next time I’ll get under three.” But life happened. Running stayed, training slipped away, and the dream sat there waiting. When I entered the Tokyo ballot after completing the Sydney Marathon last month, I knew the odds were slim. More than 360,000 people applied. When the acceptance came through, it felt like a sign. A second chance to chase that goal properly.

Today’s run felt like the real start of that journey. I went out early in Keilor Park, cool morning air, a bit of wind, perfect running weather. The plan wasn’t to smash it, but I settled into a strong rhythm and before I knew it, I was moving well - pain free! Cotton came along for today’s adventure too, which made it even better.

Fifteen kilometres later, I had what I’m calling a PB for this new stage of training. My younger self once ran a half marathon under 1:30, but that was more than a decade ago when I was 22. This time around, with a different body and a different mindset, it felt like the start of something new. My average pace was 4:24 per kilometre, with my last kilometre the fastest at 4:14. The course wasn’t flat either, about 113 metres of elevation gain with some rollers that kept me honest. My heart rate averaged 159 bpm, which told me I was working but still in control.

What I liked most about this run wasn’t the numbers, though. It was the strength I felt in the back half. Normally when I push the pace, I fade. Today the splits stayed steady, and even when the breathing got heavier, I was able to hold form and finish strong. That is the kind of run that builds belief.

I’m writing this blog to keep myself focused, but also because I know there are others out there chasing similar goals. If you are aiming for a marathon PB, or maybe to break 3:30, 4:00, or 5:00, I hope following along gives you something useful. I have been through the highs and lows before, and I know I will face them again in the weeks and months ahead.

This is just the first step. The next five months will be about stacking runs like this, building strength, and sharpening up as March gets closer. Some weeks will flow, others will fight back, but that is the process. By the time Tokyo comes around, I want to stand on that start line knowing I have given it everything.

For now, I will take today as a win. One run down, plenty more to come.

Tip of the Week
Do not overthink your training in the early weeks. It is tempting to chase fast paces right away, but the real key is consistency. Focus on showing up, building a routine, and keeping most runs controlled. You will get fitter from stacking weeks together, not from one hero session.

Next week, I am heading out for a fun 21K with a friend. We are aiming for somewhere between 1:30 and 1:40. Stay tuned.
