Radio 1 DJ Greg James gave his best effort at setting a record for the Most swimming trunks pulled on over clothing in 30 seconds, but unfortunately he wasn’t quite fast enough to take home the title. This left the record up for grabs when the Guinness World Records Live!Tour stopped at the Queen Elizabeth Olympic Park on Sunday.
20,000 visitors to the iconic sporting venue were given the opportunity to attempt various sport-related records, including Fastest time to pump a bicycle tire and Most aerobic step ups in 30 seconds.

Over the course of the day, the records were broken an incredible 14 times in total.
