Here is one I randomly made up last week that turned out to be really great! 40km loop, starts at the bottom of Muswell Hill, goes through Barnet Gate, north of Hadley, Cockfosters and Arnos Park. Its a bit hilly which makes it a great training route. It gets quite scenic and low traffic around the halfway point. Only thing to watch out for is that it takes you out on the A1 right after Barnet Gate.
