Morton arrived on the Champs Elysees in the early hours of Tuesday morning after riding 5,510 kilometres and 65,500 metres of elevation to arrive at the finish six days ahead of the Tour de France peloton.
The gruelling challenge was to raise money for the World Bicycle Relief charity, with Morton bringing in A$683,547 over the course of the endurance race against the Tour de France.
It was an emotional end to the epic 18-day trek as Morton was reunited with his wife Rachel and his father who had travelled to meet him at the finish line.
The 29-year-old completed each of the 21 stages of this year’s Tour de France as well as the transfers riding solo and unsupported.
As an experienced ultra-endurance rider Morton was able to overcome his fair share of extra challenges before the Paris finish, including serious knee pain and blisters which forced him to throw away his cycling shoes early and instead ride in a pair of sandals.
After battling through the Pyrenees, Morton dug deep with a final 579-kilometre effort from Bordeaux to Paris, clocking in more than double the length of any one stage of this year's Tour de France, the longest was 249 kilometres.
World Bicycle Relief celebrated the achievement of Morton and the massive injection of funds from the donations he elicited to the cause with his inspiring ride.
“Everybody at World Bicycle Relief has been blown away at Lachlan’s mammoth effort on our behalf," said Allison Dufosee, CEO of World Bicycle Relief UK. "We have many fundraisers who undertake challenges to raise funds for us, for which we are incredibly grateful.
"When considering a challenge, thoughts are usually about the distance and how long that will take. However, the thousands of recipients of the bicycles that Lachlan has raised through incredible global generosity have no choice about the time or distance of their challenge.
"They race from the moment the sun rises until sunset. The addition of a Buffalo Bicycle into the hands of a child will raise up that girl, boy, family, and community, giving mobility to those who have only ever walked.
"On behalf of all at World Bicycle Relief, our gratitude goes to Lachlan, his team and family, EF Education First, Rapha, and everybody who has contributed to this incredible activation. Chapeau to all!”
