Ooh! Can I come???
I'm planning a London Pootle in Spring, but might have to limit the numbers a bit, as I've been getting quite a bit of interest! Dunno how Her Maj's Finest might take to an organised group getting together in a public place..
I'm always up for an urban adventure. I love just pottering around, looking at stuff, exploring, discovering little hidden secrets. London surely does have so much to offer.
I have a loop that starts down by me; Poplar in east London, then follows the River Lee up to Springfield Park, then over to Finsburg, and along aforementioned the disused railway line to Highgate. Then, it's only a short distance to Hampstead Heath, for some spectacular views of the city. Then, you've earned some really good, long, fast, scary road descents, down into Camden. Along the canal to Paddington Basin, then down across Hyde Park and along to the River.
You could also do a nice flat river ride, along the Thames, from the City, to Canary Wharf, then on through the industrial bit to Silvertown, and across on the Woolwich Ferry ( a real treat!). Back along the south side, past the Dome, to Greenwich. Stop for a beer or snack, then head back into town, either via Deptford, or through the tunnel and up through the Isle of Dogs.
I do have several other routes, but that's just a couple to give people an idea. Using the River or canals are a really good way of avoiding traffic, and having a quieter, more peaceful ride.
I think I might actually go for a pootle later on!
