Tricky conditions caused chaos at the penultimate round of the Cyclocross World Cup in Fiuggi, Italy.

Sunday’s warm conditions caused the frost of previous days to melt, causing muddy and slippery conditions in many areas of the course.

The main victim of the conditions was Toon Aerts (Telenet Fidea Lions), with the Belgian suffering a two fractures to his shoulder after crashing into a tree on the sixth lap of the race, ruling him out of the World Championships in Luxembourg in two weeks time.

There was also a bad crash in the women’s race, with Alice Maria Arzuffi (Selle Italia-Guerciotti) colliding with the same tree as Aerts. Despite having to be carried off the course on a stretch, Arzuffi suffered no broken bones.

The men’s race was won by Wout Van Aert (Crelan-Charles), who extended his lead at the top of the World Cup standings, while the women’s race was won by Marianne Vos (WM3 Pro Cycling).
