Laura Byng dodgem
Recruitment consultant Laura Byng, 28, from Southend, completed the bone-shaking 25-hour feat at the town's Adventure Island fun park.
Along the way she was joined by friends - and they killed time by orchestrating synchronised dodgem displays.
Miss Byng said: "It was mostly enjoyable but when we got to 4am, it was freezing cold and there was nobody about, I thought 'what am I doing?'
"My friends joined in for an hour or two. We would start off bumping and have a bit of fun then we would come up with routines to entertain ourselves."
The existing record was held by Austrian Sebastian Bosch who went for a 24-hour spin in 2007.
Miss Byng beat this by an hour and must now wait for official confirmation that she has made it into the Guinness Book of World Records.
Along with teacher Cherylanne Saywell, 37, she hopes to complete The Mongol rally, driving 10,000 miles over five weeks, later this year. They plan to raise £10,000 for Haven Hospices in Essex.
