Not if the line is drawn on curved surface. It is very tough to run tight turns fast. It takes a toll in energy. Look at some of these tracks with 5 f turf sprints (turf tracks usually being inside the dirt thus tighter turns) The horses have a hell of a time holding that turn sometimes and its hard unless a horse is really got a big muscular right side, a bit unbalanced based on our counter clockwise ways of running. Heck look a track athletes that run the 200m. Not many like the inside lane, even if the track is slanted (all good ones are) to allow gravity to play a role in holding them in that turn.
