Vaclav Kosnar first became aware of Ice Cross Downhill in 2009. He was in Quebec at an ice hockey tournament at the same time the Red Bull Crashed Ice event was taking place, and he was immediately hooked. He contacted some of the Czech Republic athletes in 2015, and they told him there was a Riders Cup event in Wagrein-Kleinarl, and it was there he had his first race. Kosnar also enjoys hockey, mountain biking, skiing and motorsport. He is an economies student and also works for his dad's company as a lorry driver.
