Decided to do one last bit of the Loop before the clocks changed and the daylight hours became too short for it to be done safely. It was a warmish day and I worked up a bit of a sweat, losing around half a kilo all in all.
Section 9 is a long one at around nine miles and is pretty much entirely level, although it was a bit muddy especially near the end. It includes Bushy Park with a large wildlife collection, including deer (which are being culled now to control their numbers) and coots.
You also go over what is left of Hounslow Heath, which was a notorious haven for highwaymen, but the route is poorly marked here, and the Inner London Ramblers are discussing with Hounslow council about changing the path to follow the River Crane instead. Most of it has now been built on and the only daylight robbery you'll see now are the car parking charges.
As you go through Donkey Wood and the duck boards, you're under the Heathrow 27L/09R flight path, with aircraft passing over you around every minute and you can read the aircraft numbers.
