not been as far as on fen land coursing,but been in several places you mentioned shadow,,the fields we sometime run are like big padocks mate,,ha nothing like your big land way few obsticals then they no excuses for the dog...
west lothian Stirling and yorkshire is equal distance from me and ive run a lot in the areas mentioned , but to be honest and truthful the hares a stronger in parts of yorkshire ive run , not sayin they shit in west Lothian or Stirling just not as good as further south probably cos they run to death further south JMOP.
depends on where you run if the hares are we
