I was planning to rent a car to be able to go further north, but given the probability of poor weather in November, maybe Pentland is a safer bet for us. Could I then get away without a car? Could anyone offer an opinion on public transport? Adding on few miles of running to get there shouldn't be an issue, as long as we are not talking about running along a motorway.

You can get a number 4 bus out to Hillend which is an ideal starting place to begin a round of the Pentlands. You could do a complete circuit and come back to Hillend or run down to Balerno, Bonaly or Swantston and get buses back into the city from there.
http://lothianbuses.com/timetables-tickets-maps/timetables/4 for bus routes and times.
If you were feeling energetic you could run to Balerno and then run down the path that follows the Water of Leith all the way into and through the city centre. It's about 7 miles from Balerno to the city centre. The Water of Leith is a really nice run (and down hill all the way of course ;=)).

I'm not sure there are many races in mid November. If there are you'd probably find them on the interweb if you put in something like "marathon November" or suchlike.
