The running track is already mapped correctly as an area, in this case a multipolygon ( https://www.openstreetmap.org/relation/2534285 ).

You don't need to duplicate the multipolygon's tags, or a subset of them, on the inner or outer members of the multipolygon.

Please ensure that you have read and understood the following before you edit any more athletics tracks.

If you could explain what you are trying to do and why, I will try to help you. Most facilities for track and field in the UK could do with being mapped more accurately.
