…and the Suit That Didn\u2019t Fit After<\/strong><\/h2>\n\n\n\n

What happened this week<\/strong><\/h3>\n\n\n\n

On September 21, I ran the Colmar Half Marathon with two goals:<\/p>\n\n\n\n

    \n
  1. finish in under 1:30, and<\/li>\n\n\n\n
  2. finish faster than my boss.<\/li>\n<\/ol>\n\n\n\n

    I achieved one of those goals. I missed the other by a small but meaningful margin. My time was 1:31:54<\/strong>\u2014close enough to feel the edge of what\u2019s possible, and far enough to know I\u2019ll need a smarter push to break through.<\/p>\n\n\n\n

    I ran the race fasted<\/strong>, and I didn\u2019t eat until 23 hours after finishing<\/strong>. By the time I had breakfast the next morning, the total fast was about 36 hours<\/strong>.<\/p>\n\n\n\n

    After the race, I took an electric rental car and drove to Lyon for business meetings, with mandatory charging stops along the way\u2014one of those modern travel sequences that forces you to slow down whether you want to or not.<\/p>\n\n\n\n

    The travel + wellness thread<\/strong><\/h3>\n\n\n\n

    This race was a checkpoint in a longer experiment: can I train and perform consistently while traveling for work, without needing a complicated \u201cperfect day\u201d routine?<\/p>\n\n\n\n

    Fasted running has become normal for me, not dramatic. The bigger challenge isn\u2019t willpower\u2014it\u2019s building a system that holds up through hotels, airports, client dinners, and unpredictable schedules.<\/p>\n\n\n\n

    The half marathon was proof that the base is real. It also showed me what needs refinement if I want to level up\u2014especially with my bigger target still ahead: a fasted marathon under 3:30.<\/p>\n\n\n\n

    The moment that surprised me<\/strong><\/h3>\n\n\n\n

    Somewhere during that France business trip, I had a very practical realization: my suit was suddenly way too large.<\/strong> Not \u201ca little loose.\u201d Too big in a way that makes you grateful you own a belt.<\/p>\n\n\n\n

    That was one of those signals you can\u2019t argue with. Scales fluctuate. Photos lie. But a suit that used to fit well and now doesn\u2019t? That\u2019s a real-world data point.<\/p>\n\n\n\n

    What changed after the race<\/strong><\/h3>\n\n\n\n

    After Colmar, I reduced mileage and kept fasting, but I changed the timing of meals to avoid locking into a single rhythm. I also shifted more of my training toward bodyweight workouts and resistance training<\/strong> to support muscle retention and strength.<\/p>\n\n\n\n

    The goal wasn\u2019t just to be lighter. The goal was to improve body composition\u2014replacing fat with muscle\u2014while keeping performance moving in the right direction.<\/p>\n\n\n\n

    What I learned<\/strong><\/h3>\n\n\n\n

    Missing 1:30 wasn\u2019t failure. It was feedback.<\/p>\n\n\n\n

    This week gave me two kinds of proof:<\/p>\n\n\n\n

      \n
    • performance proof (I can race fasted at a strong pace), and<\/li>\n\n\n\n
    • lifestyle proof (something is changing enough that my clothes are noticing before my brain fully catches up).<\/li>\n<\/ul>\n\n\n\n

      It also reminded me that training isn\u2019t just running volume. It\u2019s structure. It\u2019s recovery. It\u2019s strength. And it\u2019s being willing to adjust the plan instead of clinging to it.<\/p>\n\n\n\n

      Next week\u2019s tiny focus<\/strong><\/h3>\n\n\n\n

      Keep the engine, build the frame: one short resistance session this week that you treat as non-negotiable\u2014like brushing your teeth.<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"
