Peak speed for an ICBM is in the ballpark of 6-7km/s (any faster and the payload would go orbital), and it takes about 10 minutes to accelerate to that speed. That's New York to Moscow in around 20 minutes.
So, a sub 1,000 miles from shore can hit you faster than you can get out of the blast range when you include a modest detection > reaction delay unless your sitting in an airport. It's vaguely possible you could get into a bunker in that time period, but unless you sleep in a bunker even that's not really viable.
However, by setting up things to respond in the event of a nuclear attack it does not really matter if you take out DC / Moscow as the other subs can respond anyway.
