Cycle network sign

Tried a new local walk today. Not particularly attractive - following the old railway track from Walsall to Lichfield, now part of the Sustrans cycle network. Some interesting parts though including a couple of these signs along the way. There are apparently 1,000 along their routes. Never seen one before, very colourful. Ironically there were far more walkers than cyclists on the route, and not too many of those either. A welcome change.
