Paul Merkes

Paul is originally from the Netherlands and like every child over there he got pushed on a bike as soon as he could walk. And like every kid from the Netherlands, as soon as he was able to run he turned to football (the European football). After many injuries he turned to mountainbiking, even though there are no real mountains in the Netherlands.
