When is positivity in leadership toxic? Endurance leadership lessons

ENDURES with Suzanne Rath · Jul 2, 2026 · 6m

Ultrarunner Harvey Lewis ran 111 hours with two broken ribs and a torn hamstring, and he was still smiling. That’s not toxic positivity, it’s proportionate positivity- backed by a body that had already done the work. In this episode I unpack the difference between optimism in leadership that replaces hard truths and optimism that holds them, using Harvey’s mindset and my own experiences as the lens. I breaks down what makes positivity land as strength instead of denial: acknowledgment first, room for dissent, proportion to the moment, and agency over empty reassurance.
