Allan,
$0.02 here. IF spraying the grass color is an option, a masking piece held just off of the track surface, will let the paint mist around it just a bit (depending on the distance held from the track). That will give a 'softer' edge to the line between racing surface and greenery...a bit more like how it appears on the verges beside a road-racing course, or some road-racing courses...OK the ones in my head.
Good luck with however you do it, cause it's looking great.
