Hi Trevor - you just need to click on the Map Type selector (rather than hoving over it to display the map type options). This will bring up a panel with more details about the different map types, including a link to the cycle map key.
I can get the cycle map ok but I need the legend to see what the different colours on tracks mean & the symbols for the map. Around Ledbury near Hereford there is a cycle track with red block squares on it & I cannot find what this means, I have tried the legend on OSM but it is not listed.
To get the key for the Cycle map, click on the Map Type selector and you'll see the Key link next to the Cycle Map button.
How do I find cycle map legend
