Training Tracks - Acreage Size + Dimensions

[rowellc]

I have 150 acre farm. I am contemplating putting in a horse training track, but I need to get a feel for how much acreage should be set aside for such a track as well as track dimensions.

Any info pertaining to this matter would be greatly appreciated,
such as length of straightaway, turns etc... I know these are general questions, but more specific info would be appreciated as
well as width of training track and dirt depth.

Thanks, [glow=red,2,300][/glow]
