Colin Duffy is a rock climber from Broomfield, Colorado. His passion for rock climbing began at a fitness center at age five. He later began climbing competitively and outdoors at age eight. Colin is a 10-time USAC youth national champion across all disciplines. He won gold medals in lead climbing at the 2017 and 2018 IFSC Youth World Championships followed by a silver medal in lead in 2019. In 2020, he won the IFSC Pan American Championships and became the fourth, and youngest member of the U.S. Olympic climbing team. Colin also enjoys the freedom and spirit of climbing outdoors. His biggest outdoor accomplishment to date was a single day in the Red River Gorge when he sent both Pure Imagination (5.14c) and Southern Smoke (5.14c). Along with this, he’s sent numerous V13 boulders and has his sights set on several new projects.
