Otherwise, you might try this workout about 2 weeks out in place of your normal long run. Add an easy warmup & cooldown. Then, run 4 miles at goal pace + 1 minute immediately followed by 4 miles at goal pace. For me, the 4 miles at goal pace felt very much like the last 4-5 miles of my half marathon race. And, the pace was identical.
If you do that workout, just make sure you take an extra day or two more than normal as easy days to make sure you recover fully.
Whoa! Abort! Abort!!
Sorry for not being clear on my suggested workout. It is an 8-mile continuous run. The first 4 miles is at 1 minute slower than goal pace (goal pace + 1 minute). So, if your goal pace is 6:15, do the first 4 miles at 7:15. Then, with no rest break, continue into the last 4 miles at goal pace, or 6:15.
Warmup & cooldown as necessary before & after.
You can also do a 10-miler (5 + 5), or 12-miler (6+6), but to be honest, with your mileage I would suggest the 8 miler. That is all I needed when I ran 1:17 and I was doing a bit more mileage than you. It was a solid workout, but not over the top. And, like I said earlier, when I hit mile 9 or so in the race, I immediately thought back to that workout and felt "this is exactly what my legs felt like then, and I knocked out 4 miles at goal pace" It should give you some confidence during the race.
I also agree that you know your body best. Avoid the "blitz adrenalin start" in miles 1 & 2, and you'll be fine.
