Train for the
Rim to Rim
A free field guide to one of the most dangerous and underestimated hikes in North America. What the canyon actually demands, and how to be ready for it. The framework, not a day-by-day plan.
Free Field Guide
Eight pages of field-tested framework, built to be scanned, printed, and put to use. The three non-negotiables, how much training runway you actually need, and the hydration and fueling that keep you ahead of the desert. Drop your email and we'll send it over.
What's Inside
A guide, not a prescription. The canyon's demands laid out plainly, and what it takes to meet them.
Keep Training
The guide gives you the framework. The actual work is where OAT comes in: periodization, exercise selection, and progressive overload.
