  2. A “woman’s intuition” is a real thing that modern neuroscience is only beginning to understand and measure! Here are some key neurological factors that contribute to female intuition: 🧠 Larger Mirror Neuron System: With more active anterior cingulate cortex and superior temporal sulcus areas, women can more accurately interpret nonverbal cues, better anticipate the needs of others, and navigate complex social dynamics. 🧠 Higher Inter-Hemispheric Connectivity: Enhanced communication between the brain’s hemispheres allows for more integrated and holistic processing of information, contributing to a nuanced understanding of complex situations. 🧠 More Active Anterior Cingulate Cortex: Crucial for error detection and judgment, enabling women to make quicker and more accurate assessments in various situations. 🧠 Stronger System 1 Thinking: Often referred to as the “gut feeling” mode of thought, which is fast, automatic, and relies on heuristics and pattern recognition. 🧠 Enhanced Emotional Processing: Higher gray matter volume in the anterior cingulate gyrus, insula, and hippocampus underlie women’s heightened emotional awareness, empathy, and interoception—awareness of internal bodily sensations. These brain regions play critical roles in emotional regulation, processing, and memory, contributing to enhanced emotional and empathetic responses.

  3. Imagine if your brain fundamentally changed every week. For women, this isn’t science fiction—it’s reality! Because estrogen and progesterone are powerful neurochemicals that significantly change female brain physiology, mood, and cognition as they ebb and flow throughout the month. That’s right… four different brains, four different realities—every👏 single 👏month👏! Here’s a simplified overview: 🧠 Menstrual Brain: Lowest E/P, lower metabolic conversion of brain fuel, less activity excitatory/mood boosting neurotransmitters, more sensitive to stress, more introspective/intuitive cognitive state. 🧠 Follicular Brain: High E, higher metabolism, up-regulate serotonin/dopamine/epi/norepi/glutamate neurotransmitter activity, better focus and mental energy, enhanced EQ. 🧠 Ovulatory Brain: Peak E, peak energy/focus, peak mood, peak emotional intelligence, enhanced communication skills, more social cognitive state. 🧠 Luteal Brain: Low E/high P, up-regulate GABA, neuro-plasticity, neurogenesis, microglial activation, enhanced IQ and memory consolidation. This monthly brain cycle affects every aspect of a woman’s life, yet it remains largely ignored by mainstream medicine. Ignoring this fact means misunderstanding half of humanity’s mental health and cognitive potential.

  2. 15:12:30 🧡 11 days ago, there was zero chance I was going to race Leadville. I was still processing my very public failure at Western States. I just wasn’t ready. @drmeganroche disagreed. She told me that I was not only ready to race…I was ready to chase history again. As soon as she convinced me to go from a “hard no” to a “soft maybe,” she said that she couldn’t sleep from excitement. How cool is that? She believed in me so much that it impacted her REM cycles. That was the push I needed to go for it. Leadville 2025 was just going to be about sharing as much love as I possibly could, while also totally obliterating myself. I didn’t make a spreadsheet. I just shared last year’s, and said to add 30-60 minutes. I genuinely didn’t think a record was remotely possible. Love goes a long way. Megan paced me the last 23 miles, my partner in obliteration. As we flowed at mile 95, I got emotional. “You saw this is me when I couldn’t see it in myself.” She responded, “I’m so proud of you” for the 800th time. Implied: TAKE A GEL AND GO FASTER. @run.doctor paced the 15 miles before that, fresh off his course record at the Ouray 100. I don’t have any videos of us kissing, but I promise that I wanted to when he dumped ice water on my head at mile 70. Mom, Dad, Leo, and Ollie rounded out the crew, bringing the belief, yogurt pouches, and trucks. Ollie’s middle name is “Hope” after Hope Pass, the crux of the race. Leadville magic is real. I’m not sure where this came from. But then I think back to mile 57, descending off of Hope Pass. Hundreds of racers stopped on the out-and-back course… and they said they loved me. I screamed it back: I LOVE YOU ❤️ Thank you, for everything. P.S. Failure is cool 😎

  3. What does the Pain Cave look like? It looks like Powerline Climb at mile 80 of Leadville, with pitches over 20% grade at nearly 11,000 feet altitude. What does it sound like? For me, it sounds like @drmeganroche saying “I am so proud of you” over and over. Before last year, every Leadville record attempt was scuttled around Powerline. It’s just so hard to run that high for that long, and the GOATs of the past are the GOATs for a reason (even if they didn’t have our advantages of high carb, bicarb, and plated shoes). In 2024, I barely survived the climb, almost passing out at the top. In 2025, though, I had a not-so-secret secret: Megan is the best coach in the world. She started pacing me at mile 77, and I went silent. I knew the Pain Cave was coming. It’s dark. It’s scary. It’s where I failed so emphatically at Western States. Megan’s voice filled the silence. “I’m so proud of you.” “I love you.” “We’re making history.” “I”m just talking, don’t respond.” I went stealth mode before the race, only telling a few loved ones that I was doing it. My goal was to absolutely obliterate myself, and to share love while doing it. Or, as Megan told me before the start line: “time to redecorate the Pain Cave.” So what does the Pain Cave feel like? The easiest way to describe it is a deep part of your brain screams STOP STOP STOP, a signal from billions of years of evolution. It feels more reptile than human. Megan countered that screaming with love. She bedazzled the the Pain Cave. We put 7+ minutes on my 2024 ghost in the final 23 miles (and infinity minutes on my Western States ghost, who is still panicking somewhere outside Foresthill). 100 milers will always be a trip into the Pain Cave. Megan helped me rediscover that the blood and tears that inevitably splatter all over the walls can be used to paint a big, bright heart ❤️ Coach Vince Lombardi famously said that “Winning isn’t everything. It’s the only thing.” Utter BS. I have the best coach in the world, and she taught me the truth: “Love isn’t everything. It’s the only thing.” ♥️💜💙🧡 Video by brilliant @codybare_ 🔥
