Welcome to Jelle's Marble Runs! Jelle and Dion Bakker are two brothers from The Netherlands who have created the world's most celebrated marble-race competitions. In 2016 they founded the legendary ‘MarbleLympics’, in which 12 different teams compete in all kinds of exciting disciplines to become the reigning champion. Another captivating competition is the ‘Sand Marble Rally’ where individual marbles push themselves to their limits on most exciting race tracks made of sand. JMR has revolutionized marble-racing by offering an unimaginably good production quality in their videos with a lot of attention to detail. They work with a talented commentator from the U.S., Greg Woods, to even further boost the entertainment.
