There are a couple issues with your changeset. One is that you have tagged an area as grass that from imagery appears to mostly be orchard. Also, the XC course you mapped is self-overlapping (ie repeats some parts of the route), and it's not clear how much of it is actually paths, or just running through the orchard. Ideally in a case like this you'd want to map the paths, then make a route that joins paths together in a particular order. (see https://wiki.openstreetmap.org/wiki/Tag:route%3Drunning) Happy mapping!
