Scotsman Mark Beaumont is planning his attempt to beat Andrew Nicholson's 123-day record, starting his journey in Paris on July 2.
Mr Beaumont plans not only to eclipse the record, he wants to shatter it by going ''around the world in 80 days''.
Mr Nicholson, a former Olympic speed skater, set the record between August and December 2015, pedalling 29,179km at an average of 236km a day.
The journey took him through 25 countries.
Asked about the possibility of making the round the world trip in 80 days, Mr Nicholson said such a time would require something he had little of - back-up on the ride.
''Eighty days is a hell of a daily average.''
Mr Nicholson said the right rider, if they could avoid being hit by cars, getting illnesses in places like India and had the ''absolute ideal support'', could possibly do the ride in that time.
That would be ''quite a contrast to the way I did my trip''.
Mr Nicholson said on his 123-day ride he had support for nine days in Australia and four in India.
In Australia that involved ''a very basic camper van'' his wife drove as he rode in 40degC-plus temperatures.
Support meant the rider could travel lighter, did not need to worry about navigation, trying to find bike shops if there was a mechanical problem or making sure there was accommodation at the end of the day.
With enough money, a rider could have their own cook to protect against food-related illnesses.
He said Mr Beaumont had a big profile in Scotland - ''a huge following'' - and his previous expeditions had been well sponsored and supported.
He said round-the-world rides varied in their levels of support.
Mr Beaumont had done a ''solo'' ride through Africa, although a camera crew and minders accompanied him.
''The nature of these long distance events is they're in a fuzzy stage where are they supported or unsupported?
''The chances are in 15 years' time it [the round the world ride] will be some sort of structured race, and it will either be unsupported or fully supported.
''Even with the best of support, 80 days would be a heck of an achievement if he manages to do that.''
The third of Mr Beaumont's five legs of his journey will take him from Invercargill to Auckland.
