In the Copper Canyons of northern Mexico, the Rarámuri have always run distances that shouldn't be possible, fueled by chia seeds stirred into lime water. Most runners have heard some version of that story. Then everyone went back to neon powders and dextrose.
We kept thinking about the chia. It turns out the old recipe holds up: omega-3s, fiber, minerals, steady energy. Real food you can drink. It just needed one fix the canyon runners never had a mill for: grinding the seed, so your body can actually get at what's inside.
