On Tuesday, Boston University distance runner Zach Prescott ran a mile in four minutes and 43.2 seconds. That's an okay time for a varsity athlete, but it's a great time for a a runner who's simultaneously juggling three lacrosse balls for four full laps around a track. That's exactly what Prescott did in setting a Guinness World Record for fastest "joggling" mile, breaking the old mark by a little more than half a second. “There’s a random cool community of joggling. It’s a nice little niche,” Prescott, a senior accounting major, told The Boston Globe. For the record, Prescott's fastest mile time when not handling balls is 4:19.
