HELSINKI (AP) -- Thor Hushovd of Norway says he will retire from professional cycling after the world championships in September because he's struggling to be in form.
The 2010 world champion, known as a strong sprinter, says on Friday he needs ''a bit of a holiday.''
The worlds are in Ponferrada, Spain.
The 36-year-old BMC rider began professional racing in 2000. He rode the Tour de France from 2001-11, winning 10 stages.
One of Norway's best cyclists, Hushovd has been plagued by the aftereffects of a virus illness in 2012, which kept him from racing for about a year.
This month, he dropped out of the Criterium du Dauphine after the third stage, saying he wasn't feeling good.
