It is an epic challenge that marks a milestone in the legacy of Jane Tomlinson.
This June, her widower Mike and a team of sports stars will travel thousands of miles from London's Olympic stadium to the Christ The Redeemer statue, in Rio de Janeiro.
It marks 10 years since Jane rode more than 4,200 miles across America, her last big challenge.
Jane's journey took her from San Francisco to New York in 10 weeks. She endured searing desert heats, gale force winds and the exhaustion and illness that came with terminal breast cancer.
Despite barely being able to move some mornings, she cycled for up to twelve hours a day.
Mike Tomlinson is doing the challenge alongside TV presenter Charlie Webster from Sheffield and former rugby league international player Keith Senior, who will join the team in Brazil.
They will cycle from the Olympic Park in London, 88 miles down to Portsmouth, where they'll get the ferry to Le Havre in France.
There, they have to cycle more than 1,100 miles to Lisbon before taking a flight to Recife in Brazil, before cycling the final leg of the journey - more than fourteen hundred miles to the Christ the Redeemer statue in Rio.
The team have set aside around six weeks for the challenge - the latest achievement in the name of someone who continues to inspire all these years on.
