How long should my training sessions be?

When I go out rollerskiing (or skiing), how long should a "normal"
workout be? I usually only rollerski 1:00 - 1:30 per session. Should
I eventually be doing numerous, long 2:30 - 3:00 sessions in
preparation for races of that length? I've always felt I haven't been
doing all I should in regards to LONG distance training.

Also, does anyone know of any videos on the web showing dryland hill
training like hill bounding, etc.

Thanks!!

I am sure you will receive all kinds of replies dealing with
periodization , intensity, etc., but ultimately the answer is as long
as you have time for.
Skip the boring dryland hill bounding and go for a bicycle ride or a
trail run. Keeps training much more fun and interesting.
