I thought Findo's definition was correct - as evidenced by the published figures for the 2250m RWY14 at Leeds.
TORA - 2113m
TODA - 3169m
Basically, get your wheels off the ground before the tarmac runs out and the next obstacle you come across is the best part of another 1000m along.
What that obstacle is, I've no idea. Local talk has always been that if you depart from 14 at Leeds, put the wheels up, climb no further and maintain runway heading, the first obstacle you hit is the Alps!!
