I Documented Every Problem in My Half Marathon Training. Here’s How I Solved Each One—and PR’d. (opens the original)
Read excerpt
Shortly after the 2024 Boulderthon Half Marathon, I got injured. A pinched sciatic nerve took me out for three months, and after that I had to start from zero. Rebuilding my running base was hard, knowing I used to be able to move so much faster than my current fitness level would let me. So when I decided to sign up for my next race, the 2026 SeaWheeze Half Marathon, I was in my head about it, worried about getting hurt and benched again, so it’s not surprising that I wanted to make sure to pro
My HRV Was Concerningly Low. Improving It Helped Me Have My Best Training Block to Date. (opens the original)
Read excerpt
This past winter was brutal. By February, it was already going on for too long, and yet the temperature was somehow still dropping. Running outside was nearly impossible, just as running on a treadmill was becoming unbearable, and in the midst of that, after months of dispersed runs, I committed to rebuilding my base to prepare for my first training block of 2026. Because my fitness wasn’t improving, I started paying close attention to my stats: my heart rate data, my sleep data—and, more specif
Make Your First Marathon a Little Easier By Learning From These Classic Mistakes (opens the original)

After My Blood Donation Went Wrong, I Consulted a Cardiologist: Here’s How Runners Can Time Them More Safely (opens the original)
Read excerpt
Once my appointed nurse pulls the needle out of my vein, I try to sit up to free my spot for the next blood donor. Right away, a hot flush washes over my body, and I immediately fall flat again. Very calmly, the nurse pulls a bag of ice from a nearby cooler and places it behind my neck, telling me to stay horizontal as long as I need. “Does this happen often?” I ask, closing my eyes to stop the dizziness. He nods and says, “Every so often.” I’m perplexed, as I’ve donated blood before, and while
I Tested an Expert-Backed Jet Lag Plan Before My Destination Race—and I’ve Never Recovered Faster (opens the original)
Read excerpt
Even if I don’t always fall asleep in a plane, at least I’m lucky that, at 5’4”, I’m decently compact and can fold myself into a pretzel even in the narrowest economy seat. I’m also quite certain that it’s not an ideal shape to stay in for hours when traveling to a race. My latest one, the SeaWheeze Half Marathon, is on the West Coast in Vancouver, British Columbia, while I’m based on the East Coast in Easton, Pennsylvania—which puts a six-hour flight and three time zones between me and the star
