Maarten van der Weijden Foundation (Netherlands) – World Open Water Swimming Association

The Maarten van der Weijden Foundation raises millions of euros for cancer research through extreme swimming events performed by 2008 Olympic 10K Marathon Swim gold medalist Maarten van der Weijden.



The Maarten van der Weijden Foundation is a non-profit organization established by leukemia survivor Maarten van der Weijden of the Netherlands. Its mission is to raise money for cancer research with the ultimate goal to rid cancer of the world.

Why it was nominated

Based on the success of raising over 6 million euros in his 195 km Elfstedentocht Swim, Maarten continues to raise the most money by any aquatic athlete in history. In 2021, he set a new record for the longest continuous swim in a counter-current pool with a time of 32 hours 20 minutes in Eindhoven, Netherlands and the longest distance in a 24-hour swim in a pool, and is currently training for the Elfstedentriathlon, a non-stop 200 km swim + 200 km cycle + 200 km run to raise money for former, current, and future cancer patients.
