"I wasn't sure, actually, because it was so quiet when I crossed the line," said Dylan Sorensen, the UNC assistant track and field coach.
Sorensen broke the world record for running a mile while dribbling a basketball in May on his 30th birthday -- but that had since been broken several times.
Coming into Wednesday, the record was four minutes and 33.75 seconds. Soerensen finished with a time of 4 minutes and 33.73 seconds.
"I felt confident that I could do it again but I needed purpose for why," he said.
After thinking for a bit, Soerensen said that purpose became clear. He decided to raise money for the Forever Tarheels program - which benefits female student-athletes at UNC.
"I have five sisters," he said. "I grew up with a single mother and I have seen women fight my entire life for everything they have. That is a big reason why I am and coaching women also further excites me to do that because I see the same glimpses and we believe in them so much."
