I suppose it depends what you're looking for...
I live in Hornchurch and generally play on the same section of roads around Essex.
I'm happy to ride hard for 60-90 mins and then go home, or grab a drink and go home.
Because of the density of population you need to be prepared to go out early though- this time of year you need to be out by 7am, although if you're dedicated get up at first light. Also be prepared to look out for the filth.
They know the roads and we're sitting targets.
From Chigwell I'd head to Abridge, down to Stapleford, up through Ongar, on through Fyfield and out to Dunmow- turn back on yourself and head back towards Sawbridgeworth and then divert to Chelmsford....
..once you get towards Chelmsford and the twisties run out literally u-turn and ride the same road back but carry on toward Hatfield Heath, then into Harlow, off to Epping, through Theydon Bois and back to Chigwell!
I'd be game for a wobble out with you one Sunday morning
