At this point I'm not sure whether I'm looking towards crits vs road races, so I know that's a little limiting in determining what I should be doing. But again, my question is really just at what point (that point being defined in terms of what my big ride mileage is at, or how many weekly miles I'm putting in, etc) should I start adding in things like group rides, the 1 hour max sustainable speed rides chasm54 was talking about, etc into my training and how exactly should I go about that?
