Completed 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. I’m the founder of the United World Challenge, and this December, I set out to row 5,000 miles from Hawaii to Australia by myself. After 126 days at sea, I successfully reached Australia completing the final leg of my solo journey across the Pacific Ocean. This expedition was a zero-waste mission aimed at raising funds and action to help solve the ocean plastic crisis.

Thank you for being part of this mission and for sharing this story with your followers and community. Together, we’re making momentum to stop ocean plastic and inspiring a more courageous world.

Let’s make waves!

Can you imagine spending months alone at sea in a rowboat?   

This December my friend Tez Steinberg will attempt something unthinkable: rowing from from Hawaii to Australia, solo and non-stop.  

He’s on a mission to raise funds for ocean plastics solutions.  

Today is day one of this campaign. Check out the link in the comments!  🚀

I’m so inspired by Tez – and when you check out his video, you will be, too. Will you join me in supporting this mission that our world needs so much?

When my friend Tez’s dad died by suicide in 2016, he did something incredible to process the loss: he rowed a boat across the Pacific Ocean by himself.  

Now Tez is preparing to row all the way to Australia, while sharing the story live to help solve ocean plastic. The row begins this December, but I’m already inspired and can’t wait to see what happens next.  

Check out his video here!

On Tuesday, April 23, 2024, Tez Steinberg, founder of the United World Challenge, reached the shores of Australia, successfully completing the second leg of his daring solo row across the Pacific Ocean to raise awareness and funds to combat the growing ocean plastic crisis.

While rowing 2,700 miles from California to Hawaii during his first expedition, Tez Steinberg encountered vast amounts of plastic pollution. Inspired to address this issue, he left his position at Deloitte Consulting and became the full-time CEO of United World Challenge. Together with the nonprofit’s leading partners such as AG1, Ocean Conservation Network, Hakkoda, The International SeaKeepers Society, and CRDC Global, his second journey, a 5,000-mile solo row from Hawaii to Australia, was a zero-waste mission aimed at gathering critical data for ocean research and raising awareness about the ocean plastic crisis.

Tez documented the effects of global warming and El Niño on ocean temperatures for researchers at Scripps Institution of Oceanography and other leading institutions. His expedition collected eDNA data, providing a “fingerprint” of biodiversity and insight into microplastic prevalence. This research sheds light on the impact of microplastics on marine health and the mystery of where most ocean plastic goes.

In addition to research, United World Challenge led a global crowdfunding campaign to support infrastructure projects with partner Sungai Watch. These river barriers prevent plastic from entering the ocean in Indonesia, a region heavily impacted by plastic pollution.

Tez’s 5,000 mile journey faced challenges such as towering 15-foot waves, intense tropical storms, and prolonged periods of high temperatures exceeding 100 degrees. Per the Ocean Rowing Society, Tez successfully completed this leg of the Pacific when he passed across Australia’s farthest east land barrier directly south days before. Due to extreme conditions while attempting to cross the Great Barrier Reef, he required a 36-mile tow on the final day, before rowing to land under his own power.

Despite these obstacles, he documented his journey for a feature film and engaged with real-time photos, Q&A videos, and blog updates for his following of over 52,000 on social media. 

“The ocean plastic crisis is a monumental threat, not only to marine life, but to our entire world,” says Tez. “It feels insurmountable, but like I remind myself, one oar stroke doesn’t seem to make a difference, but two million strokes will take me across the Pacific. Consistent, tiny actions show that no ocean is too great to cross.”

Brand Guidelines:

Shorthand for “United World Challenge” is “the Challenge.” Do not abbreviate “United World Challenge” as “UWC”.

Each $1 raised in our crowdfund stops 30 bottles worth of plastic (equivalent to 1.5 pounds) from entering the ocean. Our partner, Sungai Watch, build river barriers that catch all types of plastic. Bottles account for only a small portion of that overall catch.
