The fastest 20 metres carrying 300 kg on shoulders is 6.88 seconds and was achieved by Derek Boyer (Australia) at the Gold Coast Show on the Gold Coast in Queensland, Australia, on 2 September 2011.

Event was organised by a company called Neo NetWise and all funds raised (from donations etc) went to a charity for children
