Alex Honnold was 31 years old when he made the free solo ascent of El Capitan that appears in Free Solo.

How that age is calculated

• Alex Honnold was born on August 17, 1985.

• His historic free solo of the Freerider route on El Capitan took place on June 3, 2017.

From August 17, 1985 to June 3, 2017, he had not yet reached his 32nd birthday, so he was 31 at the time of the climb documented in Free Solo.
