Cyclo-cross Worlds: Vos not sure of start on Saturday

The 2015 women’s Cyclo-cross World Championships will be one of the most open in the competition’s 16 year history. While seven-time champion Marianne Vos almost always starts as the favourite, this year she’s still recovering from a hamstring injury, and although she always wants to defend her rainbow jersey, she told Cyclingnews she’s still not sure she can start.
