I've managed to do a recce of the route and I've made a small change that means we'll be using a woodland path for some of the walk instead of a stony one. You can see the updated map here.
The walk is in three parts. From Eartham Woods to the Nore Hill Folly is undulating with some lovely views to the East, South and West. There were Buzzards overhead and I came across several flocks of Pheasant. There is one relatively steep uphill but nothing dramatic. There is a short section where the path was a little overgrown by brambles and nettles but not a problem for me in long trousers. Otherwise all the paths on the entire route were well-used and clearly-marked. No styles. This section has the only bit of road walking as we go through Eartham.
From Nore Hill towards Bignor hill is mostly walking in tranquil woods. There is a steep downhill to start with but, again, nothing dramatic. I would, however, suggest ankle protection and/or trekking poles. After that it is a steady, but gradual uphill towards Bignor.
At the northern tip of the walk, the countryside opens out to reveal more dramatic views to the south and west. A great place to stop for lunch. There's a bench here but I picnic'd on lush grass. From here we follow the Roman road - Stane Street - all the way back to our starting point. This time a steady, but gradual downhill. It's exhilarating to think we're following in the footsteps of 2,000-year-old travellers!
The weather is looking good for Friday. Be prepared for some wind in the exposed sections, however.
There will be at least one car at the West Town car park at 9:15 if you need a lift.
If you're planning to come, please let me know if you haven't already just in case you're delayed on the way to Eartham. Otherwise I don't need to know if you can't make it.
