Unfortunately I think you'll be very lucky to land at 10pm and get to
Blackheath by 11pm.

Paul C's route described elsewhere on this thread sounds solid but
nontheless I also think trying to do it in an hour is pushing it. If
you took a taxi I can't help but imagine you'd get stuck up in traffic
(friday night is party night after all), though this could possibly be
avoided by going round the M25, but that's just much further -
depending upon which route you used to get into Blackheath you could
end up doing almost a half circle of the M25 - which would eat up time
too.

Indeed - just worked it out very roughly on Memory-Map Navigator and it's
around 49 miles from J15 to the J3 for the M20/A20 - there's no way in the
world you could beat the direct route at that time by going that way. Or,
indeed, at most times.

One suggestion might be to get a train to Lewisham - you might possibly get
a slightly quicker train that might only call at more major stations on the
way out to somewhere further out, than a more local stopping service.
Wouldn't knock much off the time, but there might be slightly more trains to
Lewisham, and depending on where in Blackheath the OP is heading for, it
might be almost as close anyway.

And from what someone else said, going from the tube to mainline station at
London Bridge is probably almost as much of a pain in the neck as it is at
Charing Cross from the Bakerloo line. I wouldn't bother with Southwark to
Waterloo East though - a quick look on a map reveals it to be a longer walk
than at Charing Cross.
