Everyone has given good advice..

In my case:

I ride everyday.. On mondays, wednesdays, fridays and saturdays twice..
I ride a minimum 15kms on morning rides(M-W-F-S) and a minimum of 20kms on afternoon rides..
So on Mon,Wed, Fri & Sat I have a minimum milage of about 35kms..
On other week days I only ride on the afternoon(20km min)..
On sundays, I ride a minimum of 20kms(in the morning only, have to go to church in the afternoon)..

That adds up to about 200kms minimum a week..

I'm not trying to increase distance right now, but I'm trying to increase my speed.. I have improved a little bit, about 2-3kmh faster now.. I hope I can keep this up..

My advice is simple.. Enjoy your ride! And just Ride... I try not to think of my average speed, distance and all, until after the ride..
