Expedition 2 Complete! Epic 5,000 mile solo-row from Hawaii to Australia to accelerate ocean plastic solutions
Welcome from Tez
Ahoy, mate! My name’s Tez Steinberg, and I’m the founder of the United World Challenge.
On December 19, 2023, I set out to solo row from Oahu, Hawaii to Australia. After rowing 126 days and over 5,000 miles, I reached Port Douglas, Australia on April 23, 2024.
Along the way, donors from around the world gave over $70,000 to fund the United World Challenge mission to help solve ocean plastic. These generations donations funded 15 river barriers in Bali, Indonesia. These barriers are now serviced daily, turning waste into recycled respources – and are stopping thousands of pounds of plastic every week from flowing to sea.
Thank you for being part of this mission. Together, we’re making momentum to stop ocean plastic and inspire a more courageous world.
Brand Guidelines:
Shorthand for “United World Challenge” is “the Challenge.”
Do not abbreviate “United World Challenge” as “UWC”.
Each $1 raised in our crowdfund stopped 30 bottles worth of plastic (equivalent to 1.5 pounds) from entering the ocean. Together with our Impact Partner, Sungai Watch, we built 15 barriers that catch all types of plastic. Bottles account for only a small portion of that overall catch.
