The grass infield isn't a running track. I remember it quite distinctly from the last time I ran there.

Already mapped as relation/2723886

Already mapped as relation/2725261 (although neither the inner member of the relation nor your duplicate accurately separate the 400m inner boundary of the running track from the jumps area)

Already mapped as relation/1634345 (although it has an unusual value for the surface tag)

Why did you delete the polygons incorrectly tagged as traffic_calming=island, instead of tagging them correctly as area:highway=traffic_island ?

The landuse=grass area you created should have shared the geometry of the Eastern traffic island you deleted, not been glued to the bounding highway lines.
