How would I let someone access my routes
What link would I send?
Cheers in advance

Either copy and paste them the link in the address bar of the selected route, they can then use the left and right arrows to browse other routes in the top right corner, or press the share button for emails or Facebook etc.

I|f they want the file for a Garmin they will want the GPX file on the export link

Is your route marked private? If so, it won’t matter what you send them as only your account will have access.

If using the email/ facebook link check that the page icon near the address bar in not broken. If it is click and this will put the web page into compatabilty mode. Some webpages do not run well with IE8 esp. Garmins.
On a related note do you find uploading at the moment a pain in the ar$e!
