In fact, there were quite a lot of superheroes before you (let's call them so), who made it past 1,000 of activity. I myself got promoted to the Legendary rank only two weeks ago, at 1,022 of activity miles. Here is the list of a few others (and it seems to be far from complete):
defaced 1008
Lincoln6Echo 1013
mprep 1022
mcb1221 1022
I guess you might like it
That list might not make him feel happy.
This list (of the unluckiest legendary members) might make him feel better.
