Queensland's Andrew Hellinga has broken the Guinness world record for the longest distance travelled while cycling backwards.
Hellinga smashed the previous record by 157km, to set a new record of 337km in 24 hours. The record, set on Monday, is still to be officially verified.
The 46-year-old father started his ride at 6am at the Holden Driving Centre in Norwell, and by 4:45pm had eclipsed the previous world record.
Hellinga completed the mammoth ride as a fundraiser for Challenge for Change.
