From cxmagazine.com:

Sven N: ...Normally the season starts Erpe-Mere 14 sept, but I will start one week later in Neerpelt. But over the whole season I try to race I think 10 races less than last year because I see that the young riders are doing fewer races than me and I must try to be good at the end of the season also. So 30-35 races is enough for me in the winter now. For the last years we raced about 45 races in a season. That is a little bit too much. There’s no time for training anymore so you see that the condition is going a little bit down. It’s better to train a little bit and have some more rest so you can be good at the end of the season.

30-35 races??  WOW.
