Over the winter I was lifting heavy twice a week, on Monday & Thursday, and riding the other days. I take a polarized training approach on the bike, so a couple interval/race days a week and the other days in zone 2. This worked out well for me. During the racing season, the Thursday workout switches from heavy lifting to a speed/power emphasis (power snatches, some one-legged work, kettle bell swings, etc). On weeks when I want to be fresher for an important weekend race, I skip the Thursday weight workout and either rest or do an easy day on the bike (usually the latter).

So my schedule would usually look like this.

Monday - weights, heavy
Tuesday - zone 2 ride
Wednesday - interval workouts. Either a longer one after work, or doubling up with a short workout on the trainer at lunch and an outdoor workout after work. May include a weekday crit if there's one available.
Thursday - weights, speed/power workout; or active rest if important race coming up.
Friday - zone 2 ride
Saturday - road race or long group ride with a mix of intensities.
Sunday - road race or some other type of ride, usually with some sweetspot/threshold work.

So most weeks that ends up being 5 days on the bike, but some of that is pretty easy. Total time is usually in the 8-10 hour range for the bike and another 2-4 hours in the gym.
