Today’s guest is someone who pushes limits—not just in distance, but in grit, landscape, and life. Meet David Calder.

Dave calls Alberta’s Rocky Mountains home now, but his journey begins on Canada’s east coast. A native of Cape Breton, he’s gone from coastal trails to alpine ridge-lines. On LinkedIn, he describes himself as an ultramarathoner living in the mountains—and occasionally “blowing stuff up” in his work as a driller/blaster at a nearby quarry.

In today’s episode, we’ll dive into how David’s background—his grit forged in two coasts—shapes his approach to ultra distance, resilience, terrain strategy, and life beyond finish lines.

From hydrating alpine summits to pacing in storms, you’ll hear how he thinks in kilometres, miles and meters, and why his path might challenge how you see what's possible.
