About 3 years ago when I started I was doing 3-4 rides a week - mostly about 10kms and my longest ride each week would be about 20kms.

Now I ride 6 times a week...
This includes a race of about 30-35km each week (unless its a TT which is only 20-25km) plus a warm up and cool down of about 15-20kms as well.

I try and do one ride of about 50-60kms when the weather is nice, and the other rides are about 20-25kms, or an hour on the spin bike.

Not getting much outside time at the moment due to midwinter light and bad weather so am on the spin bike more than I like.
