Thanks for the info.
I use the BVW to get to and from some of the other bridle ways or to Pitsford for a circuit and a coffee.
When they cut the hedges it's a nightmare!! Even with Slime tubes I have to pump the tyres up a few times until they seal up.
You can avoid the tunnels by going over the top, but it's more fun going through them.
If you are at the southern end, it's been tarmac'd now. (Windhover to Kings Heath)
