KC Lightfoot is the son of Anthony and Kim Lightfoot. He also has three siblings. Lighfoot’s nine best marks in the pole vault all come from indoor meets. While attending Baylor University, he studied Kinesiology and Exercise Sciences. He recently moved back to his hometown in Missouri to train under his high school coach. When he was a teenager, he and his family built a pole vault runway and pit in their backyard. When he was in high school, he took a photograph with Sam Kendricks at a track meet as a fan; five years later, they were teammates, both pole vaulters on the U.S. Olympic team to Tokyo.
