Then, if they got a full tank of JP-7 around NYC, that gives them a one-way range of 3250 miles, which is less than the 2999 nautical miles of LGA -> LHR. The SR-71's range is a hair over 3200 nautical miles. Getting a full tank of the special JP-7 or landing around LHR would be do or die time, because that would be just about bingo fuel.

Is the 3200nm range while at cruising speed or for max speed? The link mentioned it was in afterburner for a long period.

They're approximately the same speed.
