OK - I'm sure this has been done to death (if so then point me to the threads etc - I have done a search, but wasn't able to really find what I was after!).
I usually try to train 3-4 mornings a week for around 45-60 mins before work.
I then go out on the weekend for a longer ride (2-2.5 hrs).
During my weekly rides would I be best to focus on particulars (i.e. hills, speed, etc) each ride or combine them all in each ride?
I'm really looking to be able to increase my longer rides on the w/ends - using my weekly rides to build/train etc.
