This digital mapping site was tipped in August/September 2009's 'Cycle', CTC's magazine. It's built on the ubiquitous Google maps and looks not unlike bikely, that I think I've mentioned here before. The writer of the letter says it's "American based but covers the UK too". There are too many of these route recording sites, but that doesn't mean this one isn't good.

The specific route I've linked to starts in Creekmouth, Barking, but appears to cross the river there - where there is no means to do so. It then zig zags all over the shop.
