Seven days. One hundred kilometers. When I set this challenge for myself, the number sounded almost intimidating written down. But broken into pieces and spread across two runs a day, it became something I could actually wrap my legs around.
Here's exactly how I did it.
The Strategy: Split the Day, Split the Distance
The secret wasn’t one heroic daily run. It was two manageable ones.
Every morning I laced up for an 8k, and every afternoon I went back out for another 7k. That’s 15 kilometers a day, but it never felt like 15 kilometers. By splitting the volume, each individual run stayed short enough to feel almost easy. My legs got a recovery window in between. My mind never had to face one long, grinding session.
Two small bites instead of one huge mouthful. That was the whole trick.
What the Numbers Looked Like
By the end of day seven, my running app told the story in clean blue bars: nearly identical heights, day after day, climbing steadily from 05/17 to 05/23.
- Total distance: 91.9 km.
- Average daily: 13.1 km.
- Consistency: every single day landed in the 14-16 km range.
That consistency is the part I’m proudest of. No massive spikes, no collapsed rest days where I talked myself out of going. Just showing up, twice a day, every day.
The Mental Health
The hardest run of any two-a-day isn’t the morning one. It’s the afternoon one, when you’ve already done your kilometers and the couch is calling. What kept me honest was the simple math hanging over my head: skip the afternoon 7k, and the 100k goal slips out of reach.
Knowing the target turned every afternoon into a non-negotiable. The challenge held me accountable in a way that pure motivation never could.
The Final Push
So here I am at 91.9 km, with just over 8 kilometers between me and triumph. Technically I only need 9k to close it out.
But I’m not interested in squeaking across the line. Tomorrow morning I’m heading out for a 10k finishing strong, breaking 100, and giving the week the exclamation point it deserves.
What I’d Tell Anyone Attempting This
If you’re staring down your own 100k week, here’s what worked for me:
- Split your daily volume into two runs. It’s psychologically and physically easier than one long effort.
- Keep the daily number consistent. Aim for the same range every day rather than overachieving early and burning out.
- Let the goal hold you accountable. On the days you don’t feel like it, the math will pull you out the door.
- Finish strong. When you’re close, don’t just clear the bar sail over it.
One hundred kilometers in seven days. Tomorrow morning, it’s done. 🏃
