Peter Nelson II

Pete is an ultrarunner, endurance race founder, and wellness innovator whose life embodies the true spirit of SISU—unyielding grit, resilience, and purpose in the face of challenge.

After discovering the transformative power of sauna and contrast therapy in his own recovery journey, Pete set out to share those benefits with others, ultimately co-founding SISU Sauna Co. in Ohio. A father, lifelong athlete, and winner of the Antarctica 50K Ultra Marathon, Pete pairs peak physical performance with deeply restorative practices. His mission extends beyond products—he’s building a movement rooted in community, recovery, and wholehearted human potential.
