The most balls juggled is 11 and was achieved by Alex Barron (UK), who managed 23 consecutive catches in what is known as a "qualifying” juggling run. This feat was achieved at Roehampton Squash Club, London, UK, on 3 April 2012.
Alex, 18 years old at the time of the attempt, spent 2 years practising this feat-a record which had not been broken for 16 years. On the day in question, he spent 4 and a half hours in a squash court in his Easter holidays trying to reach his target. He was getting tired when he kept managing 7 runs of 21 catches when, finally, he achieved this number! Alex also jointly holds the record for Most balls flashed by a juggler, although for his attempt he used beanbags, achieving one throw better than a twelve-ball flash, making a 13 bag flash.
