Hi Bernard, many thanks for that. I will ensure that I read the url's you sent me so that I can avoid causing more issues in the future.

The Wales Coast Path, whilst it does share some coastal distance, is a separate path from the North Wales Path which ventures inland from the coast. However in future I will ensure that I add relations rather than double-mapping causing navigation issues.

My apologies for my ignorance - as I created this as one single line, I assumed that deleting it would remove all traces, however as you say this doesn't appear to be the case.

Please could you point me to a specific point where this is still in error (or inform me what I am looking for, i.e. how can I tell that there are 2 overlaid paths) and I will rectify this.
