Grindspan: Hosted by Brian Thomas

Welcome to GrindSpan, hosted by Dr. Brian Thomas.

Ultra-endurance is rarely conquered with loud bravado. It’s shaped by quiet craft: patient training, thoughtful pacing, and learning to move through the hard miles.

Here you’ll find honest dispatches from 50-mile, 100-mile, and multi-day trail efforts—along with field notes on training, race-day decisions, gear, physiology, and the mental side of endurance.

Miles. Mind. Movement. Welcome to the span.
