M25 route

Hi All. I've now completed a complete cicumnavigation of the M25 clockwise, doing it in five seperate sections. Dartford as a starting point makes a lot of sense, but the whole route is a long trek. Two halves of Dartford- Uxbridge / Uxbridge-Dartford would make good sense-both being well served by trains back into the Smoke. Waltham Cross to Godstone/ Godstone to Waltham Cross would also be poetic in that it makes the big circle starting and finishing at zero lattitude and has the furher advantage of breaking the hills of the South across two rides.

The premise was to stay as close to the M25 whilst avoiding A road. So this meant at least two steep downhills in Surrey and one killer uphill (in my case Sandridge Hill, Gravelly HIll and Titsey Hill respectiely).
Highlights were the Dartford Bridge crossing and the route under the flight path of airlliners within the perimiter of Heathrow, with a lot of good views over fields and spinney in between.

I didn't reach the sopphistication of tracking the route with Garmin, but I aim to get a route up within the next fortnight. Google Maps let me down at a couple of locations by indicating roads which were actually not publically accessible www.bikehike.co.uk provides Ordnance Survey maps and www.openstreetmap.com also provides good clarity for cycleroutes.

So M25 impressions:
pylons; water towers; shivering horses in damp fields; baying kenelled dogs; spent tyres on ragged road fringes; oil scum on drainage ditches; nouveu riche haciendas, monster retail sheds; sanitoriums; road-grimed leylandii; bizarre hand-painted signs ( denied access, local honey here); bullish four by fours; River Crane river Darenth numerous mute sliding waterways; the occasional kestrel; heron; road-kill badger and the unceasing churn the Eddy Stobarts, Mercedes man; the grey noise of white vans transiting. I meanwhile had a journery.

would like to do it again, in whole or in part and in company.
