Why are O’BOY and Mix teaming up?
O’BOY is, above all, a project by a group of friends with a simple aim: to raise as much money as possible to donate to causes close to our hearts. To achieve this, we organise sporting, festive and charitable events, notably through our O’BOY beer and merchandise. We also want to talk openly about cancer, without taboos, and bring as many people as possible together around this cause. Our project is growing thanks to our partnerships and collaborations with hospitals such as Bordet, Saint-Luc and Delta, as well as with organisations such as KickCancer, Profitivisme and many others. It was therefore only natural that O’BOY and Mix decided to join forces to organise this race and rally their communities around a shared goal.
