The Prime Meridian, also known as the Greenwich Meridian, is the line of longitude defined as 0°. It’s the line that divides East and West. It’s also a line that I asked myself last Christmas: “can that be cycled"?”. The answer is “no” as it’s a dead-straight line with buildings inconveniently built along it's path. You can cycle quite close to it though, so that’s what we did.

If you want to walk it, there’s a well-signed path called the Greenwich Meridian Trail. The Trail is also very well described in a series of 4 books by Graham and Hilda Heap. The cycle route that I designed stays as close to the Prime Meridian as possible but avoiding footpaths and opting for quieter country roads over busy main roads. Even if you’re cycling I highly recommend the Greenwich Meridian Trail books as they’re a great guide to the interesting things to see along the way.

For the first stage of our cycle trip we started at Peacehaven, where the Meridian meets the sea at it’s most Southerly point. From there we headed north over 2 days to Waltham Abbey, just above the M25. The rest of it came in later trips covering 6 days. See the main Prime Meridian post for the full route
