Hi there,

Thanks for the edits! Just so you know, while it's allowed to create tags like "xc trail", it's best to look for an alternative that already exists, otherwise no one else will be able to understand it. 

In this case, in order for others to understand that there are trails here, you need to map the trails separately, and add the correct tags to the trails.

You can map the trails as highway=path (https://wiki.openstreetmap.org/wiki/Tag:highway%3Dpath), and if you want to create the loops, you can do that as a route relation (https://wiki.openstreetmap.org/wiki/Tag:route%3Dhiking)

Hope this helps, let me know if you have any questions!
