For some real riding, get north of the city and ride some country roads.
That I can agree with. I took McCowan out until the sign that says "Whitchurch-Stouffville". I wanted to continue further but decided to be wussy and turned around. Although, IMO, 80KM for about 3 and half hours isn't too bad for me.
Trails are ok during the week when there are fewer people on them, particularly those outside of the core (they have a smoother pavement and I can attest that Danforth -- which has some temp pavement patches -- is incredibly annoying on the butt).
