My Current Running Philosophy as a Serious Amateur
How I think about training, mileage, and long-term aerobic development — without the dogma.
Why Engineering and Running Belong in the Same Blog
The systems thinking that connects software engineering and endurance training — and why I write about both in one place.
What this blog is about
RunCode Lab is a personal publication for engineers who run and runners who build. The unifying theme is performance as a system — whether in software architecture, training structure, or daily output.
Everything here is grounded in practice. No fluff, no generic advice. Real tradeoffs, honest lessons, and repeatable systems.
