Specifically, you push the bike for 10 metres along a footpath and it is lifted over a fence by you and helpful others, then you push (I prefer to ride) across a gentle downhill field of grass for 50 metres then push it along a footpath for 100 metres, then you go over a stile (see above for lifting) and turn left along a riverbank for 100 metres and are back on the tarmac.It's all dead easy. Dellzeqq allows his carbon-thingy-bike to travel it so it can't be that bad. It takes about 20 minutes max if you dawdle and chat.
The more er, life-experienced males tend to keep a sharp eye out for Joanna Lumley who is rumoured to lurk in the bushes there but no matter how hard we look, we've not seen her yet. I am beginning to suspect she is as elusive as the beauty in the boulangerie on Le Tour in Normandy - and like the lovely Samantha of I'm Sorry I Haven't A Clue.
