At the forum today people asked for copies of maps.
The TfL Local Cycling Guide Maps (also good for walking) can be ordered at https://www.tfl.gov.uk/modes/cycling/routes-and-maps .
You should also be able to get them at libraries and information centres. The map numbers you need for Havering are 5 and 8. Central London is number 1.
Interest was also shown in Sustrans route 136, The Havering Ingrebourne Way from Harold Hill to Rainham Marshes. I will try and bring seom along to the next forum, We will also have some at the IWD on 7 March. In the meantime I have scanned it in and you can download it from here. Sustrans route 136
