Early life and education

After finishing his high school education, he travelled to Uganda as a volunteer in a gap year teaching scheme organised by Africa & Asia Venture. Cornthwaite called this "his first taste of adventure".

Three rest days were required when Cornthwaite developed severe blisters. On 2 June 2006, Cornthwaite completed the journey, becoming the first person to do so on a skateboard. This journey and another in Australia were made in association with charities including The Lowe Syndrome Trust, Link Community Development and Sailability Australia.

Expedition1000
Expedition1000 is Cornthwaite's 12-year career project to make twenty-five journeys of  or more, each using a different form of non-motorised transport.
 
From 3 to 16 April 2011, Cornthwaite and Sebastian Terry journeyed   from Vancouver, British Columbia, Canada, to Las Vegas by tandem bicycle. Neither had previously ridden a tandem bike.

On 19 June 2011, Cornthwaite began a , Guinness World Record-setting journey down the Mississippi River from source to sea on a stand up paddleboard. The journey started at Elk Lake, just south of Lake Itasca, in Minnesota. The descent of the Mississippi River took 68 days including passage through falls, dams and locks. Hurricane Lee caused Cornthwaite to leave the water for a time, lengthening the trip to a total of 82 days. Cornthwaite carried all of his provisions by securing them in waterproof bags strapped to the deck of his paddleboard. Cornthwaite's speed depended on that of the current. The greatest distance covered in one day was , just upstream of St. Louis.

In March 2012, in a fifth adventure for Expedition1000, Cornthwaite and a crew of ten sailed from Cabo San Lucas, Mexico, to Honolulu, Hawaii. The  journey took 17 days. During this time, Cornthwaite and Emily Penn (the program director of Pangaea Explorations) conducted a series of workshops on topics ranging from ocean science to social media to diagnosis of personal happiness and purpose.

During August and September 2012, Cornthwaite swam  down the Missouri River, from Chamberlain, South Dakota towards St. Louis, Missouri. He had a support crew of six but pulled his provisions along behind him on a raft. The swim raised funds for CoppaFeel!, a breast cancer awareness organization.
