What might be every parent’s nightmare, stepping on a rogue LEGO brick in bare feet, became Gabrielle Wall’s stage for a world record. In Christchurch, New Zealand, she sprinted 100 metres barefoot over scattered LEGO bricks in 24.75 seconds, a feat now officially recognised by Guinness World Records. She also practised in a kiddie pool filled with LEGO bricks in her garage, stomping, testing balance, building tolerance. 24.75 seconds later, record in hand. And she’s not letting the Lego bricks go to waste.
