World championship cyclo cross

This weekend there were the world championships of cyclo cross. It is the race of bike, but that takes place on a ground of mud. Thuse the runners use the same bikes as on road but with tires with cramps for not to slide. Pauline ferrand-prevot, a french cyclist professional, world champion of mountain bike, road race became this weekend world champion of cyclo cross. It's for to me the future of the feminine cycling in France but also in the world.
