Hello Fans,
I have changed my preparation-program for the Tour. I will
not as initially planned start on Sunday at L-B-L ans also
not on the 1st of May at "Around the Henninger Tower" in
Frankfurt.
My current condition is not one to give me chances for
achieving good placements in thos races. Therefore, Rudy
Pevenage, Mario Kummer, Walter Godefroot and I have aggreed
in a good meeting to insert a further block of training.
In this meeting also all misunderstandings/different
opinions from the past were eliminated. We all are now
pulling the same rope.
The two race cancellations do not have any influence on my
chances in the Tour. I have got a lot of training kilometers
in my legs. But I do not yet have the toughness to ride 55
km/h for an hour, as in the beginning of Fleche Wallonne.
What I am still missing, I will elaborate until the
end of May.
Yours Jan
