Now, about pacing. Some general principles, founded on the physiology and the physics that govern (1) how our bodies respond to output intensities; and (2) bike speed given the forces that have to be overcome.
First, a key point about pacing strategy under uncertainty. The uncertainty I'm talking about is our ability to precisely manage output (watts). Anytime we are managing something under uncertainty, it means that there are two types of errors and probabilities associated with each error. As applied to pacing, the two error types are (1) too much power ==> we can't sustain it for the duration; and (2) too little power ==> we could have gone faster. There is a penalty associated with each error type. If the penalty was equal for each error type, it would be simple: try to nail it right on the nose, precisely the right power (watts) that you believe you can sustain for the duration. But, there's a fly in the ointment -- the penalties are not equal for each error type. The penalty for over-pacing (too much power) by +X watts for Y minutes is that you will have to ride at -X watts for more than Y minutes to recover (the exact amount is exponential -- the higher the excess power the longer the excess recovery duration). Under such circumstances, you want to bias your pacing in favor of under-pacing, especially early in the ride.
The next point about pacing strategy is that you can gain more than you lose if you apply more power (in excess of your sustainable power) on uphill or upwind segments even though you will have to apply less power (below your sustainable power) on the downhill or downwind segments. You gain more than you lose, due to the physics of the forces you have to overcome to get the bike to move.
So, in a nutshell, you want to ride at what you think is a little less than your sustainable power in at least the first half (if not 3/4ths) of the ride. This is especially true in the case of this course, with the 1st half mostly downhill and the 2nd half mostly uphill. The reason is that applying additional power when the bike is already going fast won't get you much more speed. So, in a downhill segment it's really not smart to risk overcooking it. In the second half, you still want to avoid riding above your sustainable power because if you have to back off and recover you're going to lose lots of bike speed.
The exceptions to this general rule on the outbound leg are that I would apply more power on the two short climbs (B-C and D-E) and back off a bit to recover after you clear the crest and get your bike speed up. How much additional power to add is hard to say. If it were me, I'd probably increase my power by at least 50w on the climbs because I have a fairly high degree of confidence in my ability to manage my power precisely. If you're not comfortable with 50w, then try 25w or 20w. But, these are opportunities to take advantage of VP pacing.
Likewise, on the return leg, I would add more power on the first two climbs (F-E and D-C) and recover on the following downhills. The final segment (B-A) offers no such VP pacing options and if you can't apply full sustainable power in this critical 6.56 miles you will pay a high price because it'll cost you a lot in bike speed. Fortunately, you get a 1 mile downgrade (C-B) to rest up before you start the long finishing climb. You want to back off during this last downhill segment and take a drink of water to get ready for the last part (~20 minutes).
