Ted Leblow (

I have run Richmond. It is not the fastest course in the world, but not a time goal killer.
Beware of the race courses advertised as flat/fast. Almost everybody says they are fast unless a lot of people already know better (e.g New York). But I am yet to see a Berlin/Dubai fast course anywhere in the US that is not aided. Some come close (Chicago), but not quite. Make sure to study the elevation profile in detail.
Since BQ is allowed to achieve on an aided course, the best BQ marathon in the country in my opinion is St. George. I have not seen another marathon that produces faster times. Yet, as aided as St. George is (2500 feet of elevation drop), it still is only 2-3 minutes faster than Berlin/Dubai for a 2:30 marathoner. Most courses in the US are about 2-4 minutes slower than Berlin/Dubai.
Having said the above, I think if you are able to run without injuries by November you should be fit enough to qualify on any course.
