The parents' guide to what's in this movie.

Positive Messages

People can change, grow, and evolve by facing their fears. Everyone has limits, and everyone has two options for dealing with them: You can either accept them and live within them, or you can dare to challenge them and try to push them farther out. Achieving your goals is always going to be a process, so to keep going you must draw from what inspires you to be able to keep visualizing your goals. Life is fleeting, so you must live it to the fullest.

Positive Role Models & Representations

Millán is a great model of perseverance and endurance. He's willing to put in the hard work pushing himself to his limits in order to achieve his goal. He's a proud representative of his country, and he takes the time to give back to his community by speaking about his experiences to students. He's surrounded by a loyal and hard-working support team.


A medical exam shows a needle being inserted for a blood draw. No blood is shown, but Millán winces in pain. The death at a young age of his best friend and its emotional impact on Millán are explored.


Several kisses.


"Crap" translated from Spanish.


A few scenes show Millán using some of his sponsor's products, like Guitig water.

Drinking, Drugs & Smoking

A sports psychologist gives Millán some drops of what appears to be an essential, then implies it's helping him relax by showing footage of him communing with nature.

What parents need to know

Parents need to know that From Core to Sun is a documentary in Spanish with English subtitles about Ecuadorian Millán Ludeña's world record attempt to run a half-marathon in the deepest place on earth and then run and climb up the mountain that's the closest place on earth to the sun. It's an inspiring story of perseverance, endurance, and meeting challenges that help you grow, change, and evolve as a human being. He uses "crap" a couple of times; otherwise, there's no strong language. He and his girlfriend kiss several times. A medical exam shows a needle being inserted in his arm for a blood test; no blood's shown, but Millán winces in pain. The death at a young age of his best friend and its emotional impact on Millán are explored.

What's the story?

FROM CORE TO SUN follows Ecuadorian runner Millán Ludeña as he embarks on an attempt to set a Guinness World Record in running. In one continuous trip, he wants to travel to South Africa, where he'll run a half marathon in the world's deepest mine, about 3,500 meters (11,500 feet) below the earth's surface. From there he'll immediately travel back to Ecuador to summit Mt. Chimborazo's elevation of over 6,000 meters (19,000+ feet). Months of intense training, preparation, equipment, and logistics are needed if Millán is going to achieve his goal. We follow his triumphs and setbacks as we get to know Millán and the reasons why he wants to undertake this incredible challenge.

Is it any good?

Viewer's will be amazed and inspired by this man's attempt to run from the deepest depths to the highest heights, and while it's emotionally moving at times, it's a bit unsatisfying in the end. From Core to Sun spends a lot of time listening to Millán talk about how taking on challenges and facing fears is the way to grow and evolve as a human being, but a lack of follow-up after it's all over means we don't get to learn how he himself grew or changed after this experience. Some of the moments feel forced and manipulative, like when he's fist-pumping at the top of the lighthouse, or soul-searching in the woods.

That being said, Millán Ludeña is a terrific role model for a wide range of ages for perseverance, endurance, and pushing boundaries while you strive to meet life's challenges. Aside from a couple of uses of "crap," which kids who aren't reading carefully and/or don't speak Spanish won't notice, there's no content of concern, but the gentle pace and mature perspective make it best for patient tweens and up.
