Challenge completed a day ahead of schedule

New Zealand during the winter meant Mark was continually exposed to sub-zero temperatures, making time on the bike even more gruelling, and as he cycled through Canada and the USA, he was faced with the prospect of weathering secondary storms of Hurricane Irma.

On completing the expedition, the soon-to-be double Guinness World Records title holder commented: “This has been, without doubt, the most punishing challenge I have ever put my body and mind through.

“The physical and mental stamina required for each day was a challenge in itself, but I had an amazing support team around me.

“The success of cycling around the world in 80 days shows that what seemed impossible is possible and has redefined the limits of endurance sport.

“Each stage brought different challenges including different climates, which I had to adjust to quickly.

“Stage one through Russia and Mongolia was unknown territory, so to complete this phase and come out with a second Guinness World Records title is a real achievement.

“I am very grateful for the support I’ve received from people all over the world, from fellow cyclists joining me on the road to messages and wishes online. The experience has been incredible.”

Craig Glenday from Guinness World Records added: “Mark has once again proved himself to be officially amazing! He’s added not one but two world-beating achievements to his existing record for fastest bicycle journey from Cairo to Cape Town. Beating this iconic circumnavigation record places Mark into an elite category of multiple record holders and firmly establishes him as one of the most dedicated and determined Guinness World Records title holders.”
