May 19 (UPI) -- A University of North Carolina track coach paid tribute to one of the school's most famous alumni by unofficially breaking a world record for dribbling a basketball for a full mile.
Sorensen celebrated his birthday Friday by buying a basketball from Dick's Sporting Goods and taking it to the asphalt track at McDougle Middle School in Chapel Hill.
The running coach donned a Michael Jordan 23 basketball jersey and ran a mile while dribbling the ball in 4 minutes, 37 seconds.
The previous record for the feat was 4 minutes, 52 seconds.
Sorensen filmed his run, but it was unclear whether there was sufficient evidence for the coach to get a Guinness World Record for his feat.
