Terry Cole
United Kingdom
British juggler Terry Cole achieved the longest duration juggling three balls in June 1995. He juggled continuously for 12 hours (720 minutes) without dropping a single ball. Juggling relies on hand-eye coordination and sustained focus, and prolonged sessions also demand significant shoulder and arm endurance. Even skilled jugglers typically struggle to sustain a run beyond one hour, making 12 hours a testament to the limits of human concentration.
