Why I Started The FieldAthlete Blog

I’m Reid Matsu—a name I chose to keep my personal story anonymous, but the experiences and lessons here are as real as the dirt, rain, sweat, and miles behind them. After years spent in the military, on wild expeditions, battling through ultra races and marathons, and living the grind of outdoor fitness, I wanted a home for the ideas and hard-won guidance I’ve collected along the way.

FieldAthlete.com isn’t about hype or trophies. It’s a place to store the gear tips, survival tricks, tough lessons, and no-nonsense training advice that actually works—shared for anyone who pushes their limits outside the gym. This blog is my way to put the best of that journey in one place, plain and palatable, so you can skip the fluff and get straight to what makes a real difference on the trail, obstacle, or anywhere the terrain gets tough.
