Alvaro Nuñez has done what most people would call impossible:- 7 marathons on 7 continents in 7 days.

- A 6-day ultra in the Sahara Desert with a 35-pound vest.

- A 3,000-mile bike race across America.

- Ironman and Ultraman World Championships.

But beneath the superhuman résumé is a much deeper story: one of heartbreak, vulnerability, mental health battles, and the raw conversations he had with himself in total darkness.

In this episode of The Optimist, we talk about:- Why doing “impossible” things can’t just be about validation.

- How to channel pain, anger, and heartbreak into fuel.

- The Japanese concept of Misogi and why one impossible challenge a year can change your life.

- What it means to be a man today and why listening might be the hardest challenge of all.
